Open Brush Toolkit

The Open Brush Toolkit is a collection of scripts and assets that allow you to use Open Brush data in your creative projects.

Unity SDK

Scripts, shaders and tools for importing and manipulating Open Brush .gltf/.glb exports in Unity.

• Easily import sketches into Unity
• Brush shaders and materials
• Audio reactive features
• Examples and reusable scripts to create animations and add interactivity

Command Line Tools

Python 2.7 code and scripts for advanced Open Brush data manipulation.

• bin - command-line tools
  • dump_tilt.py - Sample code that uses the tiltbrush.tilt module to view raw Open Brush data.
  • geometry_json_to_fbx.py - Sample code that shows how to postprocess the raw per-stroke geometry in various ways that might be needed for more-sophisticated workflows involving DCC tools and raytracers. This variant packages the result as a .fbx file.
  • geometry_json_to_obj.py - Sample code that shows how to postprocess the raw per-stroke geometry in various ways that might be needed for more-sophisticated workflows involving DCC tools and raytracers. This variant packages the result as a .obj file.
  • tilt_to_strokes_dae.py - Converts .tilt files to a Collada .dae containing spline data.
  • unpack_tilt.py - Converts .tilt files from packed format (zip) to unpacked format (directory) and vice versa, optionally applying compression.
• Python - Put this in your PYTHONPATH
  • tiltbrush - Python package for manipulating Open Brush data.
    • export.py - Parse the legacy .json export format. This format contains the raw per-stroke geometry in a form intended to be easy to postprocess.
    • tilt.py - Read and write .tilt files. This format contains no geometry, but does contain timestamps, pressure, controller position and orientation, metadata, and so on -- everything Open Brush needs to regenerate the geometry.
    • unpack.py - Convert .tilt files from packed format to unpacked format and vice versa.

Render pipeline support

• This repo currently has built in render pipleline support.
• This fork has URP support.
