Lightmaps, overlaping UV elements?
show user profile  Nanne
Hello mates!

I was working on unwraping a (in-game low-poly) house and I was overlaping some of the UV element to save space on the diffuse map. Parts of this house have simular texture so it will work. However I was planing on generating lightmaps for the house, now THAT can generate problems with the overlapping elements, right? The diffuse texture of the overlapping elements are supposed to be identical but they are located at different places in the house so the lightmaps will not be identical. Am I right?

Now would it be a good solution to have a different map channel for the diffuse map and the light map? That way I can save texturespace for the diffuse and add extra detail. The lightmap on the other hand doesn't need to be quite so detailed, but can not have overlapping UV elements, right?

Well, not really a question here, rather a solution but what I want to know is if my solution is a good one or if you have a better one?

Cheers mates :)
