@Ruz You seem to be on the right track :smile: I think it'd be a good idea to just look into texel density. This will be when you can really see how your UV's will be scaled way past the 0-1 UV grid, and have plenty of shells all over the place/overlapping.
@Obscura, ah ok, just me being anal about the the whole thing, I like my uv's to look tidy and 'readable' if possible whne you say decal. you mean simple transparencies? like for adding posters on walls etc i am guessing also @Kann3d that you have to scale the uv shells past 0-1 to tile rather than tiling the texture?
