I am continuing work on my DX9 shader based engine (me and everyone else), and would like an opinion on acquiring models with complex materials. Such as a model with accompanying diffuse maps, normal maps, emmissive/glow maps, gloss maps, environment maps, etc. This of course would not be for commercial purposes, just to show off some of the capabilities of my engine. Would doom3/quake4 models be a good source? Does Crysis have a model/material format, that someone has cracked?
