What the developers have to say:

Why Early Access?

We want to create a game with a vast world where you can build almost every type of vehicle and challenges that you can imagine for both yourself and other players as well. This means that Homebrew is a huge project in terms of content, systems and features and we think that Early Access will provide us with the necessary player input to shape/improve the game.

Approximately how long will this game be in Early Access?

We want to release a stable game with the planned features in it. Since we have the foundations of our game we'll be fixing bugs and adding content more frequently in future updates. Throughout development we'll also focus on implementing some community suggested aspect. We can't give a definitive release date but once the game comes out there are plans for post-release content too.

How is the full version planned to differ from the Early Access version?

Homebrew is an open physics based sandbox and for us it'll be in a constant state of development. Some content will be added, while some may be removed to improve the overall experience. To do this we'll constantly strive to make the necessary efforts while consulting with our community first.

In the about description you'll see the things that are currently in-game and the ones that are planned in the future. Since we're still early in development we'll be focussing on eliminating bugs, adding the planned features and optimization.

What is the current state of the Early Access version?

In its current state Homebrew is already a highly playable, stable and polished game. That being said it's still an Early Access title which means that bugs may and probably will occur. If you run into issues don't think twice and contact us so that we can help you and other players by fixing them.

Will the game be priced differently during and after Early Access?

The price will most certainly increase throughout development once things get more polished. The final price will be determined once we're approaching full release.

How are you planning on involving the Community in your development process?

We're always interacting closely with our community on the community hub, if you run into any issue or have a suggestion, you can always find us there. The forum at our site is the main hub of interaction between us and the players. We read as many comments as possible and take all suggestions seriously.

[19-3-2017] Rotator bug headsup!

hi guys

We have just discovered a bug that slipped our fingers.
There seems to be a problem with rotators and flaps that are using an offset, please do NOT try to fix this yourself, if you do, save your vehicle under a new name as to not lose the original project.

This bug will fix itself as soon as the new patch is updated, within the next couple days if not tomorow.

That said, don't freak out when your vehicle has some offsetted rotators, it will be fine ;)

[19-3-2017] Goodbye Spawn-Lag! : Async vehicle spawning and bug fixes!

From the team
We've been working hard to bring a new patch which eliminates around 99% from the spawn-lag in multiplayer, we'd like to thank our beta test squad for helping us through this update, to get everything ready for a public release.

Now lets take a look at what we've been up to.

Async Vehicle Spawning
In short, we were fed up with spawn-lag in multiplayer. So we decided to put all our effort in optimizing the code, and multi-threading it where-ever we could.

If you've ever played HB13, you'll know exactly what this looks like, if you haven't, you can see it in-action here

This feature will only apply to vehicles spawned by other players, since we don't like waiting for our own vehicles to spawn! This ensures that personal spawns happen as soon as humanly possible!

You'll also notice that spawning in general has been sped up quite a bit with this update, one of the main vehicles we tested during these optimizations is RhoSigmas AN225, which he graciously gave us for testing purposes.

The spawning process used to take around 31 seconds on high settings on our test machines, now it's around 8 seconds!

This means that each vehicle, spawned by the world, or other players, will now spawn in chunks, on multiple threads, in the background (where-ever possible).
This makes sure Homebrew can continue its operations without lag, as the main thread isn't hogged up by a vehicle spawn! So you can cruise around in multiplayer without giant hick-ups.

We hope that this will improve the multiplayer experience quite a bit.

Other then the async spawning, and spawning optimizations, we've been hard at work at fixing a ton of other things as well.

BEWARE: Some of these might change the behavior of your vehicles a bit!
  • Gas Turbine Jekyll no longer able to go reverse
  • Infinite setting on the battery and fuel tank is now truly infinite
  • Fuel tanks will now lose weight upon losing fuel (as long as the fuel isn't set to infinite obviously!)
  • Ballast now correctly adds weight when the ballast was part of another assembly
  • Light color property has been changed from hex code (#FF00AA) to separate RGB float inputs (from 0 to 1), and has RGB float wires now as well
  • NaN / Infinity / -Infinity no longer throws an error on wires
  • Math box Log now takes a B-input to do log(a,b), if B is not present, it will result to log10(a)
  • Multiplayer vehicles get cached as MD5 now instead of vehicle names
  • Color coding no longer works in chat!
  • Memory boxes now sync correctly in MP
  • L/s on the fuel tank is now L/h, like the float wires
  • Spring joints now allow for negative offset and pressure (the spring length can't go below 0 for obvious reasons)
  • Extra drag on hinges removed

There's also been a ton of other fixes
  • 360 hinge not being selectable when saved in a separate assembly
  • Ballast not being selectable when saved in a separate assembly
  • Drive Hinge rotation gizmo rotating the wrong direction
  • Drive Hinge rotation gizmo rotating on the wrong axis
  • Mouse cursor disappearing when holding RMB and opening inventory or tuner in the builder
  • CoT not showing for Balloons and Blimps
  • Nene sounds always playing
  • Ramjet engine sounds always playing
  • typos (Vector trust engine, max angle instead of angle multiplier, etc)
  • Receiver working without any power
  • Whirlwind fan spinning in the wrong direction
  • Solar panel not syncing correctly in MP
  • Drive hinge + negative torque (using an e-power motor for instance) and a negative transmission value resulting in the wrong torque output (reversed)
  • Wing offsets getting doubled on separate assemblies
  • Wings not calculating correctly for vehicles someone else spawns (Especially noticeable with adjustable wings!)
  • Project files not being deleted when destroying a project
  • Empty Project folders not being deleted when you don't save anything
  • Players all looking south in Multiplayer
  • Download queue not finding the same vehicle, and redownloading it after every spawn
  • Server browser history & cache and favorites would sometimes crash mid-function if the cache was corrupted somehow
  • Shortcuts triggering in builder when typing in a name or editing a property
  • Large messages in chat sometimes not being the correct height, making it unreadable

EDIT: Fixed the bike fuel tank having 170L of fuel instead of 17L, causing it to weight quite a bit more then it should!

Thanks for the find DocOlds!

EDIT2: Found another bug regarding the wing-offset fix we implemented, that fix is now removed, and rewritten. So everything should work as expected.

Sorry for the inconvenience!

What if I have a problem?

To ensure that no issue is overseen we'll be monitoring steam, DISCORD and our other channels even more over the course of the following days. In the unfortunate event that you encounter a bug please follow these steps so that we can release a patch asap:
  • See if you can replicate the bug
  • Be as specific as possible about the issue, the more information the better. Preferably attach your output_log.txt file which can be located in: installed directory / HB146_Data folder (right click on Homebrew in your game library, select properties and then browse local files)
  • Notify us on Steam or Discord (faster response time)

And lastly,
