If we could combine Bryce, with wings, and add the UV mapping system out of 3DS Max and something like GIMP for textures and I think you would have a pretty handy program.  Keep the price down and every time someone asked the question "Which is best?", I know what I would be advising them to get.

Some people are going to say UVMAPPER would be a better mapping choice, and I can't make a case against them. It is just a personal thing. Provide both as instillation options and let people decide.
