That works too caligula, but the point of multiplaning is that with the layers seperated at a distance, you SEE the distance between them, and as the camera moves laft or right or whatever, you see the distant planes moving as well, as they would in reality. To tell the truth, I haven't used masks in Bryce, but I might try that. I know there's a way to make things transparent in Bryce though, like choosing black or blue and making just that color transparent. Hawk said something about how to do it a while back, but I can't remnember what he said to do. I've never seen anyone try to multiplane in any 3D program, and by golly, I want to be the first to do it. And as I say, I know it's possible because a couple of the trees in presets are just photos on transparent planes. I just need to find out how to do that and translate if into a full screen image. It should, if I can figure it out, give a very deep 3D effect to backgrounds, rather than having a single image as a backdrop. I get good results with a backdrop, but I want to take it further, I want to push the program, and simple 2D planes with transparency shouldn't add much to render time while acheiving a large effect. It's a very old animation technique, but no one uses it these days because the multiplane camera that Uwerks invented simply is rare anymore, and the way animation is done would make it prohibitively expensive and time consuming. But for 3D work, it seems to me to offer a technique for making deep forest scenes, city scenes and other types of scenes with real depth to them.
