Mental Ray was good at stills and simplistic animation - it had good shaders and could render stuff fast, however it became useless for film style production as it was unable to do proper FG with motionblur and DOF, which is also where it hung and crashed plenty.
I have lost many nights and lots of hair troubleshooting MR crap, and it was not for lack of understanding of raytracing. I actually tested it pretty thoroughly so I have a pretty good understanding of how to optimize it. 3Delight came to my rescue at some point and shortly after that Arnold came along and made lighting and rendering fun again. MR had its place and time, but it is long gone :) Morten > Den 21. november 2017 klokken 17:06 skrev Matt Lind <speye...@hotmail.com>: > > > A lot of people don't know this, but mental ray received a HUGE update last > year with acceleration as much as 20x for global illumination and related. > The version that ships with Softimage didn't receive this update, of course. > > After acquiring mental ray, Nvidia let it rot for a few years before > deciding they should put effort into it after all, then put significant work > into it, but not until after many people went to other options. > > As much flak as people put towards mental ray, it's actually a very good > renderer, but it requires you have knowledge of raytracing algorithms to > make best use of it.
