Parace que eles estão trazendo coisas boas do Maya para o 3dsmax.
Reveal represents several things.
1) It is a rewrite of our mental ray translation code so that it now caches objects. This means that we now have a choice between rendering the entire scene and only rendering elements of the scene (something we didn't have before). This alone can accelerate rendering by 10X for incremental changes where the translation time is large relative to the rendering.
2) Region, selection rendering. We introduced region rendering into the VFB and the region box is seen in the viewport. I think you all know what region rendering is. Also, selected objects can be rerendered independently for fast tweaks. Rerendering is automatic on changes. *isso ja tem no MR + Maya ou XSI, não?
3) We redid the VFB to better support iteration, this involves moving a bunch of the most important controls to the VFB.
There might be more, this is just off my non-technical head. We wanted to do even more but six months got in the way of our aspirations. Yes, this is just mental ray, but I don't think we restrict others from taking advantage of it.

Sobre o Rendention, acho que os usuários do VRay terão uma cópia do mesmo na próxima versão (2.0).

Esses testes são 100% baseados em trabalho de CPU e foi usado um Xeon Dual Quad, mas segundo informações extra oficial, vai funcionar com o Distributed Rendering também.
