We're facing issues with the shaders for the map tiles when building to VisionPro. It looks like there's some background conversion of the TileSurface and SceneNode shaders to a MaterialX for VisionPro when its used in Mixed Reality mode with the polyspatial packages. That process strips some of the attributes of the materials that are important for rendering (e.g. clipping, opacity,..) and results in a map that is unclipped and missing illumination or color. Any help on this would be appreciated. I didn't see any posts on this issue on the ArcGIS discussion forum.
The main warning is:
[Diagnostics] Warning: Non shader graph shader 'Shader Graphs/TileSurface' not supported or MAterialX encoding missing.
The subsequent warnings I'm seeing on editor are similar to the following for _SpecularHighlights, _Smoothness, _Blend, _Cull, _Surface, _AlphaClip.
Material "Tile Surface" with Shader "Shader Graphs/ TileSurface" doesn't have a float or range property "WorkflowMode".
