Do the generic scales of objects influence the grid snapping at all, meaning does every object need to be 512/512/512 for example or can it be some totally random scale? The box example worked by the way.
Yeah, game engines have materials, but then you'd have to make some sort of material map to separate the specularity of the different materials. So you'd be easier off just making a spec map. And Matt is right, 512² of each texture. the 512 limit means you can't use separate sheets as in: 512 for the head, 512 for the…
