Hi there Myske, I'll look at Psp and see if I can figure out how to do color masks in there... Beck, thanks, I'm glad you like it and hope it helps Jilly, glad to be of help John, absolutely, the whole idea of alpha planes really is so that you can bring in different images either that you find in image libraries, or as the next tutorial will show, that you extract from an already existing image... And because they're not models, they take up virtually no space.. That's why I got this program to create trees in Painter.. I can create very beutiful, unique, realistic trees, and bring them in and it's always 4 polygons...
