Sets a dword value at the given offset of the given vertex id in the vertex data of the specified mesh.
This function will trigger an error message if the provided vertex / offset is not valid in the vertex data of the specified mesh.
Use DX11 GET MESH VERTEXDATA VERTEX COUNT and DX11 GET MESH VERTEXDATA SEMANTIC OFFSET to ensure your values are valid.
