I'm not sure I follow you? If a person does not know what parallax mapping is I don't see how they could help. Then a gain I'm the one that is asking for help so Ill do my best to explain it.
parallax mapping AKA offset mapping
It is bumping mapping's brother. Just another algorithm to make this look very realistic with out modeling the geometry for gaming. My question is how to generate the bump maps and normals map I need in maya.
