Status: Released in
We have been hard at work updating Open Brush to the latest version of Unity and it's new XR Framework. This will enable us to keep up to date with new features that are only available with modern VR SDKs such as hand tracking and passthrough. In addition it will make it much easier to support new platforms and devices moving forward.
As this is a big fundamental change in how Open Brush interacts with devices, we need your help testing our new builds before we release it generally.
Thank you very much! Please join our and give yourself the 'Beta Testers' role from our #welcome-rules channel (click the button!) to receive important updates about new builds. We're discussing this huge change in a dedicated channel, called #unity-xr. Come and say hi!\
Remember that this is a beta release, so if you do any important work with Open Brush, please back up your files!
This section is very detailed per platform, so here's some quick links to your preferred version: Already set up? Jump to:
Our desktop build is now powered by OpenXR! To make it easy to access, we have added a new beta channel on Steam.
First, grab Open Brush from the Steam store. Once you have added it to your library, right click on the listing and choose 'Properties...'
Select 'Betas' from the sidebar. In the text box, add the access code: openbrushxrbeta and click 'Check Code'. A blue banner will appear below, confirming your access!
You can now access the openxr and openxr-experimental betas. select your desired beta from the dropdown and Steam will automatically install that version! The name of the game in your Steam library will be appended with [openxr].
When you click Launch from within Steam, make sure to select 'Launch Open Brush in OpenXR Mode'!
SideQuest have just released a new in-headset installer which you can find on the guide above! If you're using this method, simply search for 'Open Brush Beta' from within the SideQuest app to install the beta. From your app drawer, in the top right, there is a dropdown to filter types of apps. Select it, scroll to the bottom, and select 'Unknown Sources'. You will see an app called 'Open Brush (feature_xr_v2). Click it to begin testing!
Make sure your Quest is connected to your device. In the SideQuest app on your computer, search for 'Open Brush Beta'. On the app page, click 'DOWNLOAD APP (SIDELOAD)'. The app will install!
In your headset, open the app drawer. In the top right, there is a dropdown to filter types of apps. Select it, scroll to the bottom, and select 'Unknown Sources'. You will see an app called 'Open Brush (feature_xr_v2). Click it to begin testing!
Click the long link beside the name of the build you wish to use (i.e. Windows Rift). A quick reminder that Windows Rift is the build you want if you're using Quest linked to your PC!
Note: before you begin, you may need to set Oculus as your active XR Runtime. this may appear as a banner on the Oculus Desktop app. Go to Settings, General and under 'OpenXR Runtime', click 'Set Oculus as Active'. You may need to restart your PC afterwards. Double click the downloaded zip file. Press the Extract all button, and unzip the folder to a known location. You may want to use your Desktop or Documents folder. Once unzipped, open the StandaloneWindows64-Oculus folder, and double click 'OpenBrush-featurexrvr2.exe' to run the program! Windows may scan the folder for viruses as it's an unknown folder, which will prevent the program launching until complete. This is perfectly normal, and the program will launch by itself once finished.
We have created a special page for installation of the Quest beta. If you are already know what you're doing with SideQuest, proceed onwards! If you haven't used SideQuest before, please take some time to follow their on setting up your Quest for development builds.
Due to the way the Oculus Desktop store versioning works, we can't automate builds without disrupting the main build! Instead, you can access a manual build from .
In short, everything you can! The previous SDKs were woven throughout the fabric of the app, so our changes impacted a lot of features. We have over on our GitHub with suggestions of things to test (anything already ticked is assumed to be working).
If you are a GitHub user, please feel free to add a comment to our where we are keeping track of validation.
Otherwise, please join our if you haven't already and post a message in the #unity-xr channel, we'll log it on your behalf!
