Right im trying to create my own textures and trans maps for hair, by exporting them as objs, then loading them in UV MApper. However half the time i cant figure out what part of the map is for what part of the hair. Any ideas, am i doing it right. Cheers.

heyas; yes, you are doing it right. there's two routes you can go from here... one, colour your uvmap template with colour coded blocks and see where they end up when you put them on the hair. or, you could give the hair a new map while you're there in uvmapper, so you can see what's going on, and then use the new obj as your hair from now on. (you can just import the obj and save it to the hair library, i believe.)

try this texture, to get an idea what is where...
