# Unity
|
|
|
|
This article will take you through installing Unity Hub, Unity, and ALCOM (the FOSS alternative to VRChat Creator Companion).
|
|
|
|
## Set up UnityHub
|
|
|
|
Download the [UnityHub AppImage](https://public-cdn.cloud.unity3d.com/hub/prod/UnityHub.AppImage). Run the AppImage like you normally would.
|
|
|
|
Running UnityHub from [Flatpak](https://flathub.org/apps/com.unity.UnityHub) is also still an option, but it seems ALCOM has better integration with the AppImage.
|
|
|
|
First, take a look at this page from [the official VRChat docs](https://creators.vrchat.com/sdk/upgrade/unity-2022/#using-the-unity-hub) about how to install the supported Unity version from UnityHub. We'll do something similar.
|
|
|
|
1. Open Unity Hub and sign in with your Unity account.
|
|
1. Install **2022.3.22** (VRChat's current supported Unity version, at the time of writing) by running `./UnityHub.AppImage unityhub://2022.3.22f1/887be4894c44`.
|
|
1. When prompted, select *Android Build Support* and *Windows Build Support (Mono)*.
|
|
|
|
## ALCOM
|
|
|
|
vrc-get is a native FOSS package manager written in Rust. Its GUI counterpart was formerly known as vrc-get-gui, but has been rebranded as ALCOM (***Al***ternative Creator ***Com***panion).
|
|
|
|
1. Download the [AppImage from the latest "gui" release](https://github.com/vrc-get/vrc-get/releases). Pick the file named `alcom-<some version>-x86_64.AppImage`.
|
|
1. Run the AppImage.
|
|
1. In the settings tab, under Unity Hub Path, point it to your UnityHub.AppImage.
|
|
1. Create a new project and open it.
|
|
1. Go to VRChat SDK -> Show Control Panel and dock it to the main window.
|
|
1. It may open windows partially offscreen. If this happens, see [this section below](#editor-windows-appear-partially-offscreen).
|
|
|
|
Now you should be able to create and upload avatars and worlds like you normally would.

|
## Option 2. LinuxCreatorCompanion
|
|
|
|
If you need some of the GUIs, it is now possible to use VRChat Creator Companion (VCC) on Linux.
|
|
|
|
The official VRChat Creator Companion uses Webview2 (Microsoft Edge). This component is difficult to install, and doesn't run natively. Instead, you can use LinuxCreatorCompanion.
|
|
|
|
[GitHub repo for LinuxCreatorCompanion](https://github.com/RinLovesYou/LinuxCreatorCompanion)
|
|
|
|
It works by using wine to extract the necessary bits to re-embed into a native client application. While experimental, you can enjoy much easier avatar, world, and asset creation. Again, this is experimental, and we discourage you from trying this on important projects. **Remember to make frequent project backups.** Please leave any feedback about bugs or ideas on the GitHub issues tab.
|
|
|
|
To install, click the releases tab, download the zip, extract it somewhere, and run `./LinuxCreatorCompanion`.
|
|
|
|
**Note:** If you're using Unity Hub via flatpak, it will have trouble finding and opening Unity. For now, create this wrapper script, chmod +x it, and put it somewhere in your PATH, like `/usr/local/bin/unityhub`.
|
|
|
|
```bash
|
|
#!/usr/bin/env bash
|
|
exec flatpak run com.unity.UnityHub "$@"
|
|
```
|
|
|
|
-->
|
|
|
|
## Troubleshooting
|
|
|
|
### Worlds: AssetBundle was not built
|
|
|
|
This error is caused by VRCSDK build incorrectly expecting a mixed-case AssetBundle filename, while Unity outputs a lowercase filename, which fails a file existence check and causes the SDK to abort the build.
|
|
|
|
To fix this, import `WorldSDKPatcher.unitypackage`: https://github.com/thegu5/VRCSDKonLinux/releases
|
|
|
|
### Shaders fail to include some .cginc files
|
|
|
|
This can happen with Poiyomi. It's caused by case-sensitivity. You may need to edit the shader files directly. Open them in any text editor, and correct the casing of filenames.
|
|
|
|
### Editor windows appear partially offscreen
|
|
|
|
Unity may open undocked panel windows (such as color pickers and unitypackage import dialogs) partially offscreen.
|
|
|
|
Some workarounds:
|
|
- For KDE, hold the Meta key and click anywhere in the window to drag it back onscreen.
|
|
- For KDE, press ALT+F3 -> More Actions -> Move.
|
|
|
|
### Drag-and-drop does not work
|
|
|
|
Rather than using Assets -> Import New Asset or Import Package, it's normally possible to drag-and-drop a unitypackage or other asset from a file browser directly into Unity's Project pane, where it will be copied to the Assets folder.
|
|
|
|
However, if your file browser is running on Wayland, this will show "Failed copying file" errors.
|
|
|
|
See issue [flathub/com.unity.UnityHub#97](https://github.com/flathub/com.unity.UnityHub/issues/97).
|
|
|
|
As a workaround, launch your file browser in Xwayland mode. Unity will accept the file as it should.
|
|
|
|
```
|
|
WAYLAND_DISPLAY="" dolphin
|
|
```
