Re: question: uv maps and normal maps
yeah thanks for the reply guys! Thanks Hitmonlfinity I do exactly the same. I overlap the diffuse and spec to save pixels. have overlap with one normal map, but that is for the little details baked from the diffuse. I never had an issue with specular to be honest. I then have a speperate uv without overlap for the… -
question: uv maps and normal maps
Hey guys, I have a question about uv maps. Whenever I make a model, I tend to have a lot of overlap in the uvmap for the diffuse. My question is. Is it common to have 2 uvmaps: one for the diffuse and normal created from that diffuse. And another uv that doesn't have any overlap which I can use for lightmaps (in unreal for… -
Re: question: uv maps and normal maps
The diffuse was using tiling textures that were used in a lot of other places. The normal map was unique. This way, you can get unique surface information that's not in the diffuse. -
Re: question: uv maps and normal maps
We made some buildings in Hawken using different UV maps for diffuse and normals. If I remember correctly, the models had three uv maps: diffuse/spec, normal, and light map. You have to set it up in the material editor though. We were using UE3. The yellow structures were made using that method: -
Re: question: uv maps and normal maps
All your normal maps SHOULD share the same UV islands as the diffuse on one UVE set. Your light map should be a seperate UV set and everything shoudld not be ocerlapping. Yes, you can have 2 UV sets.
