I've created a hair texture in Painter, and exported it to photoshop format. By deleting the background layer I now have the hair texture with an alpha channel, perfect for transmapping. When I save this image as a TIFF or Photoshop file (which should include the alpha channel) and apply it as a texture in Poser, the alpha channel is not used as the transparency map. I do have Photoshop 4 LE, but I am Photoshop stupid. Is there a way to extract the alpha channel from my image and save it as a separate transparency map? I am using a Macintosh, BTW.
