I use 2000 X 2000 images for all my textures the way I build them is to have all the seperate sections of the texture map saved as seperate files Like the eye's, Face and body etc, each has its own file. Then I use PhotoShop to assemble the texture I want by putting each individual image in as a layer. I have a base image called BlankP4 , the layers are already made for each of the section names and I have directories on the hard drive with the same name. Then it is simply a matter of picking skin tone map, eye shade maps,Tatoos maps etc and then exporting the result as a LZW tiff. The idea you have is great but to make it more internetable try offering the layers as seperate downloads either high quality JPG or LZW Tiff format. Then everyone could build the file in the software they already have....Just an idea. Paul Hafeli
