Check out THIS comprehensive and extremely informative article about all things rendering written by Mike Seymour over at www.fxguide.com

In the words of Mike: “Once considered a commodity item in the whole CG / VFX world – rendering is now a hot topic. CG supervisor Scott Metzger jokes that one can’t talk about renderers without annoying someone. “Renderers are like religion (laughs). Rendering is a religion! Especially now in this era, which is really really exciting, there is so much going on and there are so many renderers, so much happening. To me it is the most exciting part of being in our industry right now.”
