Hey - I just thought of something...
Instead of making the image transparent for sketchy edges, I could cut it away. I'd have to cut the image around the solid shape. Here's what I mean: I am putting images of 2D people into a 3D model. The area in the image that's around the person is transparent. The sketchy edges do not show through. How about if I cut away all the transparent areas?
Is there a way to follow the outline of an object in an image and cut around it? (A way that does not make me want to pull out my hair. And quick, too. I have lots of images.)
By the way, this is for a scene from the movie I'm making. I am creating a series of short movies using SU animation. You can see the first one, Plain Sight, at TreasureInside.net The next movie has a party scene with many images of people. --- Joel
