Anyone, I am having trouble figuring out this Opacity thing. I have a .CEL in which I want to fly across the screen with a certain background(a picture). This .CEL is a picture of a character, where the bachground of the .CEL is black. All I need to do is just make the black colors in the .CEL transparent so the background of my scene shows up thru it. Is this possible? Thanks, Mike C.

I believe the upper left pixel in the image is the key color used with DECAL, but make sure all the black pixels in the BG are the same value. Otherwise, mask with Alpha and save to a alpha-supporting format, then USE ALPHA. BILL
