I don't know about the radiosity thing... Just as an example: I've been using LightWave 7 for about a year now, and one thing I've noticed is that there's alot about LW that e-on seemed to try to incorporate into Vue 4, like the parameters on tools and such. It makes me think that e-on looks at LW and thinks, "Yeah, we should do that..." Anyway, LightWave has exceptionally good lights, and particularly the volume lights are much better than Vue's, with (predictably) more options and more control. Granted, Vue 4 is a bit more intuitive and novice-friendly, but lIghtWave is much more advanced. But I'm mentioning that because LightWave also does the radiosity thing, and it does it very, very well. So, if Vue 5's radiosity compares to LightWave's in the same way that Vue 4's volume lights compare to LW's, then I'd probably be disappointed, although I'm willing to bet that Vue 5 will render radiosity quicker than LightWave does. Of course, LightWave is LightWave, and Vue isn't LightWave, and is about an eighth of the price. ;) Let's just say I'll be surprised if e-on pulls off a professional-quality, competetive radiosity engine in Vue 5... Radiosity aside, the "area light" idea (found in LightWave), would be a great idea for E-on to explore. Area lights make for some really realistic shadows, for one thing, and can be a reasonable substitute for radiosity effects.
