Pros: (1) easy to use (2) can quickly create landscapes (3) ecosystems (4) as mentioned earlier, GI and radiosity look great (5) plays well with higher end apps, Maya in my case (6) pleasant customer service experience once you find the right page Cons: (1) Production, final or broadcast quality renders are slow, although I haven't yet tried using Rendercows yet (2) renders look "noisy" to me despite tweaking; maybe I missed the anti-noise setting (3) function editor may seem daunting if you're not familiar with procedural padadigm Indifference: (1) haven't used Carrara but in my experience every program that hosts a Poser native file will have a slow / clunky response Having graduated from Bryce since Vue 4, I am thoroughly satisfied with V5I as my landscape generator and I think you might too.
