I am looking to add some variety to my biped texture maps. I can export out the model, I can export out the UV. But I can not export out any of the texture maps. I'd like to keep some of the texture and rec-olor some of the cloths. Is there a way to do this?

RMB on the HDA, select Type Properties
switch to the Extra Files Tab
look through the list of files to find the .jpg textures
