Quote - Yes. None seem to come up to Steve's UV Mapper Pro for me though.

Horses for courses?

That's true, everybody has their own favorites; but there is a workflow issue involved too.
"[Shrug] Oh well, I have UV Mapper Pro." isn't going to resolve any uv mapping issues for Carrara. I think it should have good UV Mapping of it's own...

Quote - Bit of a cost to get a UV mapper though!

See you have it backwards. When you spend money to buy Lightwave, or Modo, or Max, or whatever to make models; you don't have to go and make an additional purchase of an external UV Mapping program. It is part of the package.

Friends don't let friends use booleans.
