May I join in the spamming then? :-) Yeah, C4D is a great app. Its modelling part didn't do much for me, but texturing and lighting is as easy and more powerful than in Bryce. Pity the caustics and radiosity are available only in the Advanced Render module. OTOH, Rhino 4, the next version, will use Brazil as its module renderer (like Flamingo is now) and will have much better polygon and even better NURBS modelling abilities. :-) It's already in alpha stages. OTTH, both of them have plugins, like Max. I haven't tried XSI, Maya, Lightwave or Electric Image. Do they have plugins, too?
