green river
I am trying to use custom instance data, and I have this shader attached to a MultiMeshInstance3D node with the appropriate flag set, but I am getting an error telling me that there is an unknown identifier in the expression: 'INSTANCE_CUSTOM'
Any help is greatly appreciated!

I tried with Mobile and Compatibility modes and both produce the same error.

INSTANCE_CUSTOM is only accessible in the Vertex Shader. you can pass values from the vertex to fragment shader using a varying.
