Strange Material Error

What does this mean?

[SM5] Shader attempted to bind the Primitive uniform buffer even though Vertex Factory FLocalVertexFactory computes a Primitiveld per-instance.This will break auto-instancing.Shaders should use GetPrimitiveData(Parameters.Primitiveld).Member instead of Primitive Member.

When i try to use my prop with this material it just shows a grey checkered box instead and the material wont work.

Please share a screenshot of your material so we can see why it does not work
