UVMap issues, and ideas..

[Nova]

I know it's a paid program, but as an alternative to XNormal (Which is quite good, although hard to get a hang of), there's ShaderMap (http://shadermap.com/). It's $50 which makes it pretty useful for hobbyists. I've messed around with it a little bit and it's a little simpler to get the hang of, and modifying the cage is not nearly as complicated as XNormal.

As for doing these things in Wings; that would be great! Although, I think you'd have to make the hi-poly model first, UV that and then scale down. Wings doesn't handle UVs for added geometry that well (Especially if you start moving it around). Unless you guys meant some kind of process where the Hi-poly model wouldn't need UV maps, only the low-poly (Which is how it works in XNormal and ShaderMap).
