Hi Sketchy. i wasn't implying that a good render engine is the "be all - end all" of a 3D app. Just pointing to the fact that it wasn't low-level people that started Modo. These people have the smarts and experience... And it's a bit off-topic, but i don't like the idea of "rooms" so i disagree that Carrara is a good example of a modern interface. Modo is a much better example IMO. Doing everything in one space (with one set of tools) is more efficient. It just takes better planning when designing the UI...
