GeometryScript runtime edit material

I edit mesh using GeometryScript in runtime, but DynamicMesh-related Material node does not seem to function. SetMaterialIDsOnAllTrianglesNode and SetMaterialIDOnTrianglesNode…

After confirming it again, the material relations function, but reading in the run time of Asset where copy mesh from staticMesh node was Failure seems to fail. However, it is like Success in Construction.
I solved AllowCPUAccess of StaticMesh when I accepted a check.
