What I am wondering is whether Z-Toon is portable to other applications. In particular, I have read that Cararra 2.x has a fast rendering engine with high quality. Cararra 3.0 seems to be focusing a great deal on non-photorealistic rendering (although they claim to have also improved photorealistic rendering), and claim that rendering is 3-5 times faster than in Cararra 2.x. It seems that getting Cararra 3.0 (or even just 2.1), would be worthwhile just for rendering speed and quality alone, but would I lose the potential of Z-Toon? Dale LaRoy Splitstone
