Well, there is now a good program to translate textures from V3 to V2 and from V2 to V3. It is sold here at the marketplace and in Daz store as well i think. Great buy if you already have several textures you want to reuse with another model. As a sidenote, i remember people complaining a bit of the quality of the V3 to V2 maps (the V2 to V3 looked very good). As i don't have the program yet those other people may have better comments on the program now :)
