Modulus: Factory Automation news & patch notes

Hey Module Makers,

A fresh patch is live for Modulus today. Here's what's been fixed and improved:

Performance & Stability

• Made the Statistics and Achievements system thread safe, which contributed to the factory stopping issue

• Fixed a factory stopping issue tracked down to the Salvager

• Fixed freighters jittering

Bug Fixes

• Fixed an NRE when removing an item

• Fixed Harvester Pads throwing exceptions when undoing or redoing their move

• Fixed the GNN Gate and Buildings losing progress of non-shape resources

• Fixed the GNN Gate discarding modules when cancelling an upgrade

Other

• Pausing a monument now disables the charge and stops it from progressing

• Expanded the dynamic content panel on the Start Screen to handle multiple pages

As always, thank you for your reports, they go directly into fixes like these.

See you on the factory floor. — Team Happy Volcano

You asked for it and we’re delivering; Modulus now has official mod support, and we can't wait to see what you build. Seeing as this is such a significant update we wanted to do a proper post rather than just patch notes. So, let's dive in.

FOR PLAYERS

Subscribing to mods is simple. Head to the Modulus Steam Workshop, find something you like, and hit Subscribe. Mods load automatically when you start the game, no fiddling required.

You'll find a new Mods tab in Settings (also accessible from the Main Menu and Pause Menu) where you can see everything you have installed and toggle mods on or off.

Modulus Workshop: https://steamcommunity.com/app/2779120/workshop/

Also it is worth flagging the following:

• Steam achievements won't unlock while any mod is active

• Any save file you play with mods enabled will be permanently marked as Modded, even after uninstalling mods

• If something looks off, try disabling mods first and see if that fixes it

We've also added friendly error notifications so that if a mod causes an issue, you'll know exactly which one, no guesswork necessary.

FOR MODDERS

Modulus now runs BepInEx under the hood, which should feel familiar if you've modded Unity games before. We've put together a public GitHub with everything you need to get started:

https://github.com/Happy-Volcano/modulus-modding-samples

Inside you'll find:

• 3 sample mods walking through the basics of modding for Modulus specifically

• Documentation on Modulus' codebase

• An upload tool for creating and updating your mods on the Workshop

We absolutely can't wait to see what the community creates and then what players do with those creations in the game. Whether you're adding quality-of-life tweaks, visual changes, or something we'd never have thought of ourselves, the factory floor is yours. One More Thing in the Update: Module Preview Fix

This release also includes a fix for the bug where module previews were showing up as white squares on operator UI panels, cutters, stampers, assemblers, and on modules transported via freighters and freight hubs. This one has been reported a fair few times and we're glad to finally have it squashed. If you've been seeing white squares where your modules should be, this one's for you.

Oh and just a quick note to say that Modulus is part of the Steam Summer Sale, so if you've been waiting to build your factory, now is a great time to join the production line. You can grab the game at 25% off during the sale.

Have fun.

Hey Module Makers!

David's back with what might be the most mind-expanding episode of the Academy yet. Episode 7 is all about expert-level module production, a fundamentally different way of thinking about how you build. If you've ever felt like your factories are getting the job done but taking up way more space than they should, this one is for you. If you’ve ever seen one of Jarvs’ streams then you know what we’re talking about (hehehe).

The core principle underpins everything in this episode: the more voxels you can manipulate in one operator, the fewer operators you need.

The Standard Approach | Efficient, But Spacious

David starts by showing how most players tackle module production, using a module for the Lumite Reactor as his example. The typical approach: take a full belt of cubes, assemble to a big block, cut it into the smaller pieces that make up the module, paint and stamp the individual parts, then reassemble them.

It works. It's completely efficient, 240 cubes per minute in, 240 modules per minute out. But it requires repeating the same sequence of operations four times across a lot of operators and a lot of floor space. It gets the job done, but there's a much smarter way to think about it.

Think Before You Slice

Rather than immediately cutting your big block into individual module-sized pieces and processing each one separately, David introduces what he calls the sushi roll approach.

The idea: instead of thinking about one module at a time, think about how you could arrange multiple modules together within the big block before you start cutting. If you glue the modules next to each other, and crucially, rotate some of them, you can arrange them so their matching parts line up across the whole block. That means you can stamp, paint, or cut across the entire block in one operation rather than repeating the same operation on each individual piece.

In David's example, by rotating the modules within the block so the black parts align, he reduces the number of stamping operations needed from many down to just five, producing something he describes as a mould that the other pieces slot neatly into. One final cut at the end slices the whole block into four finished modules at once.

The result: 60 big blocks per minute in, 240 modules per minute out, and dramatically less space required to get there.

Assembling Floating Parts | You Don't Have to Join Everything Up Front

The second technique David covers is what he calls assembling floating parts, and it's a subtle but powerful shift in thinking.

In a standard setup, you might feel like you need to attach each individual piece to the main block as you go. But Modulus doesn't require that. You can combine parts together that aren't yet attached to anything, building up a floating sub-assembly, and then attach the whole thing in one go later in the production line.

In practice this means instead of using a monotoner on four separate black pieces individually, you can assemble those pieces into one floating cluster first and monotone the whole thing in a single operation. Four steps become one. Applied across a full production line, the savings stack up fast.

Putting It Together

Combining both techniques, David's optimised setup produces the same 240 modules per minute as the standard approach, but in a fraction of the space. He also uses four times less paint in the process, since painting one large piece covers what would otherwise require four separate painting operations.

Once it's working, David's habit is to clean it up into a tidy, blueprint-friendly rectangle, easy to copy, easy to place, and satisfying to look at.

The takeaway: before you start building, spend time looking at your target module and asking two questions. Which parts can be combined into a bigger volume before processing? And can rotating the arrangement reduce the number of operations needed? The answers will make your factories smaller, cleaner, and a lot more satisfying to build.

That's Episode 7! If this one made your brain hurt in a good way, drop your questions in the comments, and make sure you're following us on Steam so you don't miss the next episode.

See you on the factory floor.

Hey Module Makers,

Patch 5 is here and we want to give you a proper look at what's included, because this one is a big deal. We've been listening closely to your feedback since launch, in reviews, on Discord, in the forums, and beyond, and a lot of what's in this patch is a direct response to what you've been telling us. Let's get into it.

The Stamper Just Got a Whole Lot Smarter

The Stamper changes are probably our favourite part of this patch, so let's start here.

First up: you can now choose which module exits which side of the Stamper. If you've ever found yourself fighting your layout because the Stamper was outputting things the wrong way around, that frustration is gone. Route your resources the way your factory actually needs them.

Second: we've added a scrap behaviour toggle. This one has an interesting backstory. Back in early playtesting, we made a deliberate call to keep the Stamper running on one side even when the other was blocked. We'd seen blocked machines causing a lot of frustration early on and wanted to avoid it. But since launch, a clear group of you have asked for the opposite: the more logically consistent behaviour where a blockage on one side backs up both. You were right to ask. It's now a toggle, so you can play it whichever way suits you.

Tackling Progression Pain Points | Coolant and Freighters

We know that for some of you, coolant has felt like a wall. Managing it gets expensive fast and the sense that you're fighting your own factory rather than building it is never what we want you to feel. With Patch 5, coolant efficiency is now upgradeable in the tech tree. Each unit of coolant is used to power 16 operations, upgrading this doubles it to 32, and then 64. In practical terms, if you're running advanced operators at 120 operations per minute, you were consuming 7.5 coolant per minute per operator at base efficiency. Those upgrades cut that cost dramatically, and your coolant production will go a lot further as a result.    

On freighters: you asked for more, so there are now more. Simple as that. The cap has been doubled, and if you've ever hit that ceiling and felt your logistics grind to a halt, you'll feel the difference immediately.

Quality of Life Across the Board

A set of UX improvements that collectively make the game a lot easier to read at a glance.

The Tech Tree now has a search bar. If you've ever found yourself clicking around trying to find a specific node, that's now a thing of the past. A big shout out to Tapgiles in our Discord who had a mod up and running for this within days of launch. Thank you for showing us how much better a search feature makes using the tech tree feel.

Production icons can now be toggled on above each building, showing you exactly what it's producing without having to click into it. Great for debugging, great for getting a quick read on a busy factory floor.

Datashard notifications have been added for when your shards are consumed by auto-upgrades. A few of you have been puzzled about where your Datashards were disappearing to; they were being used for building upgrades via the auto-upgrade system, which is easy to miss. You'll now get a clear notification when that happens so nothing feels like it's vanishing into thin air.

And finally, a map fix, there was a hole in it. It is now hole-free. Yay!

We're really proud of this one and as always we are eager to hear what you think when it's in your hands.

See you on the factory floor. — Team Happy Volcano

It's been a little over a month since Modulus launched, and we wanted to take a moment to say something simple: thank you.

Watching this community come to life has been one of the best parts of making this game. The screenshots, the layouts, the Discord discussions about the most efficient way to route a belt, the community mods, and so much more! The whole team has been following along and loving every second of it.

Your Streams and Videos

We put a lot of love into Modulus. Seeing you love it back means everything to us. So, we collected a bunch of our favourite clips of your videos and streams to celebrate an amazing first month of Modulus:

Your Screenshots

We asked ourselves what better way to celebrate than to let your work do the talking. Here are some of our favourite screenshots from the past month, your factories, your creativity, your chaos:

This is just the beginning. We're continuing to grow and improve Modulus, and knowing we have a community like this behind us makes that work feel worthwhile every single day.

Your Reviews

Also a HUGE thank you to anyone who has left a review. Good or bad! The negative ones have helped us focus on what we need to improve, which directly led to Free Build Map launching last month. The positive ones mean everything to us. Your words do not go unnoticed and we are forever grateful for your love of the game. 

If you're enjoying the game, please do consider leaving a review, for a small studio like ours it makes an enormous difference.

So, from the bottom our all our hearts: THANK YOU. See you on the factory floor.

Hey Module Makers,

We’ve just pushed a small hotfix for Modulus.

• Fixed an issue where factories could suddenly stop functioning during gameplay

Thanks to everyone who reported this so quickly, it helped us track it down fast.

As always, keep the feedback coming. See you on the factory floor.

Hey Module Makers!

David's back in the Academy, and this episode is a big one. Freighters are something you'll encounter a bit later in the game, but once your factory starts spanning multiple islands, they become essential for clean, scalable logistics. Here's everything you need to know.

The Basics | Setting Up Your First Freighter

The core idea behind freighters is simple: instead of running skylines everywhere, you use freight hubs to centralise a resource and distribute it cleanly across your factory.

When placing a freight hub, pay close attention to which input dock you're delivering to. The freighter has four cargo containers, each corresponding to a dock number, so if your resource arrives at dock one, the freighter will load it into cargo slot one. Slots two, three, and four won't pick up anything unless something is connected to those docks.

A habit worth building early: always name your freight hubs clearly. Something like "Coolant Distribution" or "Coolant Deposit" goes a long way when you're managing multiple routes and things start getting busy.To configure a freighter, open Freighter Control either from the top menu or by clicking a freight hub directly. From there you assign a name, a colour, and set up its route, clicking once on a cargo slot sets it to load, clicking twice sets it to offload. Once applied, your freighter will run the route continuously without any further input.

One thing to watch: if you change what's coming into a dock, the dock still expects the original resource. To reset it, you'll need to clear the dock's contents first. It's easy to miss and can cause a freighter to get stuck holding cargo it can't deliver anywhere.

Overflow Distribution | Feeding Multiple Hubs Automatically

Once you're producing at scale, you'll often find yourself sending one resource to several different destinations. Freighters handle this more elegantly than you might expect.

David's example uses blue paint: 240 units per minute produced, split across two factories each consuming 120. Rather than trying to divide the route precisely, you can configure a single freighter to drop off at both destinations in sequence. If the first hub is full, the freighter holds onto the remainder and offloads it at the next stop. Over time, the system self-regulates, production and consumption balance out, and there are no blockages.

One thing to keep in mind: distance matters. If your freight hubs are far apart, the freighter may be too slow to keep up with production, and you'll need to run a second freighter on the same route to compensate.

Multipurpose Freighters | Two Jobs, One Route

If you're running low on freighters or just want to keep things efficient, a single freighter can handle multiple operations at once. In David's example, the freighter delivers yellow paint outbound and picks up a different resource on the return leg, bringing it back to the starting hub.

The key is keeping a close eye on your dock assignments. With multiple resources moving through the same freighter, it's easy to accidentally mix things up. As long as you're deliberate about which cargo slot carries which item, it works cleanly and saves you a freighter on the roster.

That's your Episode 6 breakdown! Got questions about freighters? Drop them in the comments,  and make sure you're following us on Steam so you don't miss the next episode.

Hey Module Makers!

David's been busy in the Academy, and we've got two more episodes worth of tips to catch you up on. Whether you missed them or just want a written reference to come back to, here's the full breakdown of what episodes 4 and 5 covered.

Episode 4 | Debugging with the Efficiency View

Episode 4 is all about one of the most powerful tools in Modulus that players often underuse: the Efficiency View.

Unlocked through the tech tree, the Efficiency View is accessed by pressing H. It recolours every operator in your factory to reflect its current efficiency, green means running at full capacity, yellow means underperforming, and red means something is seriously wrong. The goal is simple: get everything green. (Side note if you look closely everything also has a pattern on displaying the corresponding number in the key. This is so that those with red/green colour blindness can still see bottlenecks in this mode)

But knowing something is wrong and knowing where it's wrong are two different things. David's approach to debugging uses scrappers as a diagnostic tool. The logic is straightforward; by placing a scrapper at a point in your production line, you relieve the downstream pressure on everything upstream. If your operators turn green once the scrapper is placed, you know the problem lies further down the line, not where you were looking.

Working through a production line step by step, David places a scrapper, checks whether upstream operators improve, removes it, and moves further downstream until the problem reveals itself. In his example, two Cutters were outputting 30 items per minute each, but one of them was feeding into a machine that could only accept 15 per minute. The result was a blockage, invisible at a glance, but immediately obvious once the scrapper technique isolated it. The fix was simple: add a splitter and double the downstream operation.

The lesson is an important one. Even a green operator in the Efficiency View can be hiding a problem, if it's outputting at capacity but that output is backed up, the real issue is with whatever comes next. The Efficiency View tells you where to look; scrappers tell you where to stop looking.

Episode 5 |  Logistics and Organising Your Factory

Episode 5 tackles a challenge that almost every player hits as their factory scales: how do you efficiently feed multiple operators from a single belt?

David uses the dye mixer as his example, an operator that takes in 7.5 units of oil and 7.5 units of pigment per minute. Early on, one mixer is plenty. But as your production grows and you're pushing 30 units per minute down a belt, you suddenly need four mixers running in parallel to consume it all. The question is how to route everything cleanly.

He walks through three approaches, each suited to different situations.

The first is the angular approach: one resource flows in vertically, the other horizontally. Resources are split off as they pass each machine. It takes up space, but it's easy to read and easy to debug, you always know which belt carries which resource.

The second is the sequential splitter approach, and it's the most elegant. Rather than trying to divide the belt evenly upfront, you simply run the belt past each machine and let splitters do the work. When a machine is running slowly and its input is backed up, the splitter automatically redirects excess items forward to the next machine in line. No manual balancing required. As David demonstrates, 30 oil per minute feeding four dye mixers (each consuming 7.5) is handled perfectly, each machine takes what it needs, and the remainder flows on to the next.

The outputs are collected cleanly via a tunnel running underneath the row of machines, bringing everything back to a single belt. Two resources in, one resource out; compact, readable, and easy to duplicate if you need to scale up further.

The third approach compresses the layout vertically for tighter spaces, using the same splitter logic but configured for narrow corridors rather than open floor space. Same principle, smaller footprint.

The key insight across all three approaches is that splitters in Modulus are smarter than they look. They don't force an even 50/50 split, if one output is blocked, the flow automatically redirects to the other. Understanding this behaviour is what makes clean, scalable resource distribution possible.

That's your Episodes 4 and 5 catch-up! Make sure you're following us on Steam so you don't miss the next one.

And while you're putting those tips to work...

We're launching a new round of our Screenshot Contest!

It's here, Module Makers, The Free Build Map is now available in Modulus!

When we previewed this last week the response blew us away, and we can't wait to see what you build with a bit more room to breathe. From today, when you start a new save you'll be able to choose between the Classic Map and the Free Build Map; more space, logical Polyrock layouts, and no terrain constraints getting in the way of your factory vision.

The Classic Map isn't going anywhere. Two ways to play, one game. Pick your challenge. We have also tweaked the tutorial to include the fact that you can place belts through miners, as many players reported not realising this for several hours. Additionally, the update includes the following fix:

• Fixed softlock when trying to link harvester pad drone to a building

Also live today: Steam Trading Cards!

Collect, trade, and show off your love for Modulus. Cards drop as you play, so get on the factory floor and start earning them.

We Are Going Live

We am going live in just under 30 mins to show off the new Free Build Map. So join Jarvs in chat and hang out as she tries to make a more organised factory than her previous spaghetti filled attempts. 

Twitch YouTube TikTok

She will also be drawing the winner of both the Screenshot Contest merch bundle on stream.

As always, let us know what you think in the comments or over on Discord. And if there's something else you'd love to see in a future update, you know where to find us, the Feature Upvote Board is open!

See you on the factory floor. — Team Happy Volcano

Hey Modulue Makers First up WOW. Thank you from the bottom of our hearts for such an incredible launch week. Your excitement and enthusiasm around the game means more to us than we can put into words. Seeing everyone sharing screenshots, giving each other advice on optimal layouts, and just generally being as excited about the game as we are, has been absolutely awesome.

We have been listening to feedback and monitoring the Feature Upvote Board for your most requested suggestions and have begun putting a plan together to decide what's next for Modulus. There has been one particular suggestion that has come up a fair few times in reviews and forum posts, and that is to give players a way to build without the terrain constraints present in the campaign. Whilst the puzzle aspect of designing a factory around these constraints is intended, and is the recommended way to play Modulus, we do get that it isn't for everyone. We hear you when you say you want to build, copy, and blueprint more easily.

So we're adding a new map that lets you do exactly that.

Introducing the Free Build Map

In the coming weeks you'll get the option to choose between the Classic Map (recommended) and Free Build Map which gives you:

• Larger islands: more room to build and expand your production lines the way you want to

• Logical Polyrock layout: resources distributed in a way that makes sense for how you want to build, not against it

• No terrain challenges: a more open, traditional factory experience for those who prefer it

The original map isn't going anywhere. If you love the spatial puzzle and the constraint of the island terrain, that experience is exactly as it was. This is simply a new way to play Modulus, and we think it opens the game up to a lot more players.

Also in this update: A small but important tweak to the tutorial: we’re telling players more clearly that belts can run through miners. The hologram will now show the conveyor running through the miners, with updated text to match, as well as in front of them. A minor fix, but one that should make those first few minutes a lot clearer. 

We'll have a release date for the map update soon. In the meantime, let us know what you think and if there's anything else you'd love to see in a future update, drop it on the Feature Upvote Board.

Hey Module Makers!

If you've been following along with our Modulus Academy video series, you'll know that Creative Director David has been dropping some seriously useful tips for getting the most out of your factory. Whether you missed an episode or just want a handy written reference, here's a rundown of everything covered so far.

Episode 1 | Operator Efficiency

The first episode laid the groundwork with one of the most fundamental concepts in Modulus: identifying and eliminating bottlenecks.

David walked through a basic production line, four miners feeding a furnace, a cutter, and an assembler, to demonstrate a common pitfall. The miners produce 60 polyrock per minute, the furnace processes that into 15 cubes, the cutter slices each cube into 4 pieces (60 pieces per minute total), and it all looks great... until it hits the assembler. The assembler can only take in 15 pieces per minute on each input, meaning it consumes just 30 of the 60 pieces being produced. Half your output is going to waste.

The fix? Double up your assemblers. By running two assemblers in parallel, you consume all 60 pieces per minute and jump from 15 modules per minute to 30, using exactly the same upstream resources.

David also showed a smarter, more space-efficient alternative: using two furnaces feeding an assembler to first create a larger intermediate module, then cutting that bigger module into four pieces. The result is 60 final pieces per minute in a much more compact footprint. The lesson here is that the order of operations matters. Thinking carefully about which step comes first can unlock serious efficiency gains without needing more floor space.

Episode 2 | Building Ratios

Episode two stepped up in complexity, moving from individual production lines to efficiently supplying an entire building, in this case, the Basic Blue Pigment Refinery.

The key insight is that a well-run building should never be waiting on modules, and no module you produce should go to waste. To achieve that, you need to match your production ratios to what the building actually requires.

David's process breaks down into a few steps:

Check the module requirements. The refinery needs three different modules, one of them required 32 times, the other two 16 times each. That's a 2 : 1 : 1 ratio.

Match your production to that ratio. Since each module is 64 voxels (one full cube's worth), you allocate two cubes of production to the first module and one cube each to the others. This gives you 30 per minute of the first module, and 15 per minute of each of the others, a perfect 2 : 1 : 1 match.

Set your crane ratios correctly. Cranes always operate at 15 deliveries per minute, so delivering 30 per minute requires two cranes, and 15 per minute requires one. If your crane ratios are off, the building will sit idle waiting for the slower module to catch up, even if the other modules are fully stocked. Getting this right means all modules are delivered and consumed simultaneously.

Don't forget production-phase resources. Once the building is fully constructed and begins producing, it may require additional resources. In the refinery example, that's blue hexa crystals. The same crane ratio logic applies, match the crane count to your production rate so nothing clogs up or falls behind.

When everything is dialled in, the refinery produces a clean 15 blue pigment per minute. As David points out, 15 is the magic number in Modulus, everything in the game works in multiples of it.

Episode 3 | Paint Efficiency

The most recent episode tackles a resource that players often burn through without realising: paint.

David opened with an honest admission, the example setup he built was deliberately inefficient to illustrate the problem. Building the modules for the Droid Assembly using three separate painters results in 45 paint consumed per minute to produce 45 modules. It works, but it's wasteful, especially as your factory scales.

The core problem is a common instinct: make your shapes first, then paint the individual pieces. This means you're running paint through the machine multiple times across multiple parts.

The smarter approach is to paint earlier in the process, before you cut and assemble. By painting the raw cube blue at the start of the production chain, every piece cut from it is already the right colour. You don't need additional painters downstream. The result in David's improved setup: the same 45 modules per minute, but using only 15 paint per minute, a threefold saving.

For more advanced factories, David shared an even more efficient technique: combine multiple furnace outputs into one large block, paint that block once, then cut it down into smaller pieces. Because paint in Modulus coats an entire object regardless of its size in a single application, painting at the largest possible volume before cutting gives you the best paint-per-piece ratio you can achieve.

The takeaway: always ask yourself where in the order of operations you can apply paint to cover the most surface for the least cost.

That's the full Modulus Academy catch-up! Make sure you're following us on Steam so you don't miss the next episode. See you on the factory floor. - Team Happy Volcano

Hey Module Makers!

Welcome to February's Modulus Monthly!!!!

February was a massive month for us! We finally revealed our release date April 2nd which means there’s officially less than almost a month until Modulus is released to the world! Between our recent playtest (where your feedback is currently fuelling our final push of content) and our time in Steam Next Fest, we’ve been busy. It was incredible to see Modulus in the hands of so many hungry new module makers, and we are absolutely thrilled by the positive reception.

As always, we’ve been dropping teases throughout the month, so let’s take a look at what we’ve got cooking!

Auto Drag Decoration

This one has been very requested. You asked us to make it so you can auto drag decorations and you will no longer have to manually place:

• Corners

• T-sections

• Crosses

They now automatically connect to whatever is next to them. Just place and build, the system handles the rest. And that’s not all… You can now place decorations by holding left click and dragging. No more placing them one by one. No more click-click-click marathons. Small change. Big quality-of-life upgrade 💪

Auto-place Skylines

You can now auto-place Skylines between islands simply by dragging conveyors across them. Previously, you had to manually place each Skyline step by step. It worked… but it wasn’t exactly elegant. Now? Just drag your conveyor across the gap and the Skyline will place itself neatly between the islands. Cleaner. Faster. Much less fiddly. It’s one of those small changes that instantly makes building feel smoother, and once you use it, you won’t want to go back.

Achievements

Mick, our Lead Dev, has been hard at work implementing them into the game, and we’re excited to finally start showing a few of them off. It’s been really fun thinking about the different milestones, discoveries, and moments we want to celebrate as you build, experiment, and grow your factories. Here’s a small sneak peek at some of what’s coming. Note some of these may change before launch and are a work in progress.

Wrap-up

With February behind us and the major milestones crossed, we’re spending our remaining time perfecting Modulus to ensure everything is ready for April 2nd. It feels surreal that we’re only a month away! From everyone here at Happy Volcano, we want to say a massive thank you for being part of this journey. We can’t overstate how much your support has meant to us and we’re ready to make this our best release yet! Don’t forget to wishlist and follow the game, try the updated demo if you haven’t already, and keep sending in your feedback, we genuinely love hearing from you.

Hey Module Makers,

Welcome back to our Dev Deep Dive series.

In Part 1, we explored the philosophy behind the sound of Modulus, how we aimed for something rhythmic, informative, and as zen as possible. If you haven’t checked that one out yet, we definitely recommend starting there.

Today, we’re zooming in. In this part, we’re breaking down how operator sounds are actually implemented: how a single machine goes from concept to in-game audio, and how those individual sounds layer together to create the wider rhythm of your factory. Let’s get into it.

How Does a Single Operator Get Its Sound?

Jarvs:   Almut, can you walk us through how a single operator gets its sound?

Almut:  If something is already moving in-game, I’ll capture it, either record it myself or get footage from the team, and bring it into my audio software. Then I start experimenting.

I focus on what the operator is actually doing. Is it mixing liquids? Cutting? Stamping? I think about what’s moving, what’s interacting, and what that should feel like.

One important thing I’ve learned is that it’s much better to get something into the game quickly and iterate there. A sound that feels perfect on its own can completely fall apart once it’s surrounded by everything else. So instead of polishing something for ages in isolation, I prefer to test it in context and tweak from there.

And variation is crucial. If you repeat the exact same sound over and over, it quickly becomes irritating, at least for me. So once I have something that works, I build subtle variations to keep things rhythmic without becoming repetitive.

After that comes the fiddly part: dealing with the 3D game world. Operators are 3D sound sources, which means they have a defined size and distance in-game. You should hear them clearly when you’re close, but they need to fade naturally as you zoom out. That balancing act can only really be done once everything is live in the game.

What Happens When There Are 20 Operators at Once?

Jarvs:   I know nothing about the technical side, but I imagine it gets complicated when you have 20 operators next to each other and all those sounds are happening at once.

Almut:   I wouldn’t say it’s technically complicated, but it’s a lot of fiddling to find the sweet spot where everything works nicely most of the time.

Mick:   There are some aspects you wouldn’t expect. In most games, the “microphone” is positioned at the camera. That makes sense in first-person or close third-person games.

For Modulus, we had to do something different.

Because you can angle the camera downwards and zoom in and out freely, the sound can’t simply follow the camera. Think of it like a boom operator in film, holding a microphone just above the scene. That’s effectively what we’re doing.

There’s an invisible point on the ground that the camera looks at, and the microphone is centered on that point. As you zoom out, the microphone moves upward, but it stays aligned vertically above that spot. This works well for factory games, because once you have a lot happening on screen, you don’t always know exactly where a sound is coming from anyway, which lets us hide some imperfections.

The other big constraint is performance. You can’t just play sounds for the 5,000 objects that might be visible on screen. That would sound chaotic and break performance.

In some games, you can let overlapping instances stack or trim themselves automatically. We don’t really get that luxury. The sound has to work perfectly when an operator stands alone in an empty field, and also when it’s surrounded by hundreds of others. That balance is where the real challenge lies.

The “Invisible” Layer: Ambient Factory Sound

Beyond individual operators, there’s another layer at play.

Almut:   We have a separate layer of general factory noise. When there’s just one operator on screen, you don’t hear that layer at all. But as more buildings and operators appear, that ambient layer gradually blends in.

Mick:   We basically try to find a good average of what’s on screen. There are three main ambient tracks: a general factory layer, a conveyor-specific layer, and a nature layer, like subtle birds in the background.

These are evaluated at a fairly low resolution. We can’t calculate this per tile, it wouldn’t work performance-wise, so we approximate what’s happening on an island and blend accordingly.

Technically, the ambient system is sometimes “guessing” what’s happening on screen. But so far, nobody’s complained that the soundscape is lying to them.

The Zen Balance

Jarvs:   From what I hear in the community, people really love that mix, especially the nature sounds. They say it adds to the zen feeling. It’s not just a mechanical factory hum; there’s a sense of space and calm.

And it works beautifully with the little environmental details Antoine has added visually. It makes Modulus feel like more than just a factory, it feels like our factory.

Mick:   It works great… until we add the next batch of sounds. Then we go through the entire process all over again.

But it’s good to hear that right now it feels like we’re in a good spot.

That’s a closer look at how operator sounds are built and layered into the living, breathing rhythm of your factory. From individual clicks and movements to the full soundscape of a working production line, it’s all about subtlety, timing, iteration, and restraint, making sure the factory feels alive without ever overwhelming you.

If you missed Part 1, make sure you check it out. We dive deeper into the philosophy behind the overall sound of Modulus and how we shaped its calm, clockwork identity.

And if you’re curious how all of this feels in motion, you can try the updated demo right now as part of Steam Next Fest.

Hey Module Makers!

Welcome to the first Modulus Monthly of 2026!!!! January may have been a quieter month on the surface, but behind the scenes we’ve been polishing systems, improving flow, and laying important groundwork for what’s coming next.

Let’s take a look at what we’ve been working on! 

Freighters: Smarter, Smoother, Cuter

You’ve seen Freighters before, but they’ve had a big upgrade this month.

Freighters now feature:

• New animations that give them more personality

• Improved pathing, so they avoid clipping into each other

• Queueing at Freight Hubs, meaning no more traffic chaos

They’re also… surprisingly polite. Sometimes too polite.

Yes, we did briefly have a situation where everyone was waiting for someone else to go first. We fixed it, but we couldn’t resist sharing it with you.

Modulus, Any Time of Day

To kick off the year, our Game Director shared a simple reminder: Modulus looks good at any hour.

The day/night cycle continues to add atmosphere and variation to your factories, whether you’re building under bright daylight or watching your machines glow at night.

Quality of Life: Belt Dragging

Next we have a small but mighty improvement, courtesy of Oliver on the dev team.

You can now:

• Drag belts directly through operator inputs and outputs

It’s a subtle change, but one that immediately makes building feel smoother and more intuitive, and yes, the whole team got very excited about it.

Huge thanks to Ollie for this one 💪

A New Perspective on Your Factory

We’ve also added a new zoom setting that allows for much higher camera perspectives.

This gives you:

• A clearer overview of large factories

• Better readability when scaling up

• And some very satisfying wide shots of your islands in motion

As our Game Director, David, put it: “I’m loving our new zoom setting, it allows much higher perspectives.” We couldn’t agree more.

Meet Atlas

We’ve also been spending time weaving the narrative into Modulus, and that starts with Atlas.

Atlas is your liaison to The Colony, the beings responsible for your creation. Designed by our Art Director Antoine, Atlas stands apart from the bots you produce in your factory, both visually and thematically.

He’ll be:

• Your guide

• Your point of contact with The Colony

• And your biggest cheerleader as your factory grows

We already love him, and we’re excited for you to meet him properly.

Looking Ahead

January was all about refinement: smoother logistics, clearer building flow, stronger atmosphere, and deeper personality. These improvements may seem small individually, but together they make Modulus feel better, calmer, and more cohesive to play.

As always, thank you for your feedback, your screenshots, your bug reports, and your enthusiasm, it genuinely shapes how the game evolves. Don’t forget to wishlist and follow the game, try the updated demo if you haven’t already, and keep sending in your feedback, we genuinely love hearing from you.
