Thanks for that, that's exactly the type of answer I was looking for, it seems there's a lot more to do and no idea how to do it.
I have, in no particular order: 1) outfit AO bake 2) outfit shadow bake 3) outfit texture 4) outfit UVmap
And then I have the same again for additional patches of this piece of clothing.
Any helpful tips on how to begin would be greatly appreciated. I guess what I'm asking is can anyone recommend a good beginner's guide to texturing in second life?
