Hi y'all, I'm pretty much a noob with Bryce, so I'm not even sure this is possible, but I need to retain an alpha channel in my Bryce renders. Is there a way to do that? What I'm wanting to do is render a variety of pine trees on a plain background, then open the render in Photoshop or PSP, and extract out the trees to use as background scenery on a book cover. I've tried rendering against plain gray, but there's no alpha channel, so I get huge gray halo around all the little pine needles when I mask out the gray. So I could really use an alpha channel. The working cover image so far is an assembly of Poser renders and will be heavily postworked. Any help would be greatly appreciated :-) Thanks!
