Open Brush is a free, community-led open source fork of Google's Tilt Brush, a room-scale 3D painting application for virtual reality built in Unity. It lets users paint in 3D space with a wide variety of brushes and effects across modern XR headsets and desktop VR.
Use cases
- paint 3D artwork in virtual reality
- create room-scale drawings with VR brush strokes
- continue using Tilt Brush after Google archived it
- export and share VR paintings on an open gallery
- contribute to or fork an open source VR art app
- run 3D painting on Meta Quest, SteamVR, or Pico headsets
When to choose
- you want a free, open source VR 3D painting tool
- you need an actively maintained alternative to the archived Tilt Brush
- you want to modify or extend a VR painting app in Unity/C#
- you use modern headsets like Quest or Pico with OpenXR support
When to avoid
- you need 2D image editing or traditional digital painting
- you have no VR hardware and want desktop-only 3D modeling
- you need professional CAD or mesh modeling tools rather than expressive brush strokes
