Even with a little faster rendering the rendering of complex scenes is totally slow. What we need is a hybridrenderer, think about the one in Carrara. There are really good opensource renderers in the wild these days. With a pluginconnection they could be used for Bryce too.

Sure the renderer is not the only addition needed, as I said some posts before, but it is one of the most needed I think.

Bryce is not the standard 3d application for me. I allways thought about it as a creativity enhancer, but waiting does enhance nothing but only some bad feelings.
