Unity SDK: v22.0.0
Major changes (some of these are Tilt Brush features and not Tilt Brush Toolkit features):
- glb: Support for Tilt Brush v22 .glb export format, which is gltf 2.0. Tilt Brush v21's .glb1 used gltf 1.1, which is not widely supported by tools.
- glb: Support for timestamp information which Tilt Brush v22 now writes into .glb files. Timestamps are read into texcoord2 by default. A timestamp is a vec3: x and y are the earliest and latest timestamp in the stroke which contains that vertex, and z is the timestamp for that vertex.
- glb and fbx: Support for images and models from the Tilt Brush local media library; support for models from Poly.
