Materials Shading Graph Validation

>>> [ERROR] Material incoming connections check - FAIL.
> Connection to "body_mtl.baseColor" is not supported.
> Please make sure that only "file" or "aiImage" nodes are connected to materials.
Currently only "file/aiImage" and "bump/normal" nodes can be connected to the materials.
If any other nodes are connected, the validation will fail since the shading graph won't be able to be recreated on the platform.
