I have several files in .png format. They're intended as textures with opacity maps that are in the alpha channel. Does Pshop handle .png format? If so, how do I extract the alpha channel to get the opacity maps. I need to seperate them into a texture map and an opacity map. I've never dealt with .png files before, don't even know what the heck they are.
