MaterialX Shader Authoring in Blender

Blender currently supports exporting MaterialX within USD, but lacks meaningful support for authoring or executing MaterialX-standard shader graphs natively. This project aims to introduce the MaterialX standard node library into Blender's shader editor as first-class native nodes. A working execution prototype through Cycles' OSL backend will serve as the secondary deliverable, enabling round-trip evaluation of authored graphs during the project timeframe. Adding this feature to Blender will make it easier for 3D assets to interoperate with other DCCs, and will make Cycles a great candidate as the reference renderer for MaterialX.
