Normal map problem (SOLVED)

etsuja

I'm getting some pixelation/artifacts in my normal map and I don't know why... I'm using lightwave 8 normal map plugin to generate the map with world space. Are my UV's just stupid or does lightwave plugin suck at making normal maps?





I think it might be due to overlapping polies?

Looks like it's picking up adjacent or intersecting mesh parts. Such as the lines around the eyes coming from picking up sections of the eyeball meshes.

I think I might have to do some manual editing in photoshop

Well, I fixed it and it wasn't really even hard. I don't know why though this isn't even the final one. Just testing some stuff out. All I have to do now is fix the area around the nose. Think I'll just have to tweak some UVs for that

Looks like a world- or local-space normalmap, but you are mapping a character. If it's going to deform (bones, morphs, whatever), you'll probably need tangent-space normals instead.

Yeah, I've already changed it to tangent space. Lightwave appearently doesn't have a tangent space shader though.
