Chameleon, just so you know, unless I specifically state otherwise, everything I make is Public Domain. So do what it is you need to do with it, share it, whatever… so don’t worry about that with my stuff.
Secondly, when I created the UVS, all I did was apply a cylindrical UV to it in Hex. But the texture I used was just a square of tileable colour. Basically, the sarong is designed so that all you have to do is create a square of colour, and apply that, tile it if it needs to be tiled. I try, not always successfully, but I do try to keep the UVS in mind when I model anything… ever since my debacle with the UVS on the Black Rhino… I learned my lesson there
