I'm working on some eye textures, but since I don't have a program that supports transparency maps, I don't have any way to figure out how they work. I wanted to put these eye textures in the Marketplace, but if I do they'll need trans maps for the Poser users. So my question is, on a s trans map, are clear areas white with opaque areas black? The reason I'm asking is because the corneas of the eyes need to be clear.
