Dunno. Let me know what those materials are, and I'll try to give
recommendations.

I don't currently have the time to set up some LDraw->POV-Ray workflow
myself.


As mentioned before, LEGO's standard opaque plastic has a refractive
index of about 1.6, which also happens to be a good approximation for
LEGO's standard transparent plastic (both clear and tinted).
