Extend OVRTX MaterialX/OpenPBR conversion

When to Use

Use when adding supported shader nodes, sockets, texture operations, UV handling, material bindings, fallback policy, conversion diagnostics, or OpenPBR parity.

Boundary

Work in the distributed source checkout and use documented runtime interfaces. The add-on owns Blender graph discovery, conversion policy, texture materialization, USD overlay generation, binding identity, caching, and diagnostics. Do not solve unsupported graph conversion by patching the runtime or mutating the source material.
