Thanks for the reply, Pete. That's IS what I meant. So, if the alpha map is
embedded in the image, using the image as a map automatically adds the
alpha? or do you have to specify? I'm a little fuzzy on that part. I've seen
a specific gray scale image applied as a separate map for alpha/transparency
in other software.
