I'm going to need two sets of models, more or less, if I understand Normal Mapping with Blender - and then there is LOD to consider, but as far as I know Blender does MIPMapping automatically, as long as it is turned on. I think each level of LOD needs its own set of models, but I might not need the LOD levels if I just use the Normal Maps. (Really in deep water now )
LOD, MIP, LOD LOD LOD... I believe I've heard LOD so much in one post right now that I can't forget about it..
Well, I suppose the LOD, MIP or whatever you called it is all about texturing and such?
