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
