It looks like Speedtree8 PBR shader is not working with VisionOS (it appears in pink in the simulator) although it is Shadergraph… I guess maybe some node is not compatible ? Any workaround ?
That’s correct. We support a subset of shader graph features, and haven’t tested with/attempted to support the shader graphs included in the URP package (including Shaders/Nature/SpeedTree8_PBRLit.shadergraph). Just looking at the export warnings, it looks like it includes HLSL in Custom Function Nodes that isn’t compatible with the HLSL subset that we support, and uses the Baked GI Node, which we also don’t support yet. Getting that shader graph to work with PolySpatial would likely require substantial changes.
