2 ?s on my 1st Iron Knuckles DC9 repaint: alpha channels and black anomoly

My first repaint turned out very nicely: an Alitalia DC9 for Flight One's Iron Knuckles. However, I cannot figure out the alpha channel for reflections. Is it something that is part of the template, or do I have to create it? I can export an alpha channel (supposedly) to my Paintshop Pro from DXTbmp, but it is just featureless white. Also, in DXTbmp itself, no alpha channel is shown, which makes me wonder. Nothing I've read helps me so far.Also, there is a black rectangle in front of the nose wheel. I've looked at textures I have been playing with, and see nothing that would make that. Its not on other IC DC's I've seen, and I can't seem to get rid of the stupid thing.Anyway, the airplane looks good, but a little reflection would be nice, plus I would like to get rid of that black anomoly.Thanks for any help you can lend.Tim Capps
