- Autodesk showed USD import into Forge. Translates to Forge-native geometry.
- Autodesk also working on a WebGPU Hydra delegate that does PBR shading.
- A lot of overlap between the delegate above and Filament (i.e. SPIRV tools in browser)
- TBB remains an issue that everyone is keen to solve.

JavaScript bindings, need a real strategy on how to tackle them.
...
See what changes have landed in /dev that may help reduce reliance on WebAsm-TBB and its CORS issues.

Working example of WebASM build of USD with a Hydra delegate for Filament
- https://github.com/marsupial/USD/tree/HdFilament
- Working on macOS & Firefox-87.0
Ideally GitHub Pages version at https://marsupial.github.io/USD/extras/imaging/examples/hdFilament would be a live demo, but
- due to the lack of 2 http headers WebASM using threads will fail to load
- a local server.py can be used to serve the branch locally instead
- Colored Quad, Sphere, and Cube are USDA. Gold monkey rotating in circle is USDZ. PBR monkey spinning around its center is glTF.
- HdFilament shader generation is minimal and displayColor is used for primitives. Textures on monkey.usdz are not loading correctly.
- USDA loaded can be edited in the HTML: https://github.com/marsupial/USD/blob/HdFilament/extras/imaging/examples/hdFilament/index.html#L119

Goal is to have USD WebAsm branch and a WebAsm build of Filament Hydra Delegate by next meeting (April 7).
