Well, I can't get the copyrect to work with alpha in any mode . I've tried the drawimage command and the grab command. I still feel that there `must` be a way to do this quickly at run time and without explicitly reddressing each and every pixel. Could we not have a command to either zero the alpha map or copy an alpha map from another texture/image? Hmm? I'll try the feature request thing or whatever it's called today.
