大名鼎鼎的德國渲染器mental ray，是一個將光線追蹤算法推向極致的產(chǎn)品，利用這一渲染器，我們，全局光照明等其他渲染器很難實現(xiàn)的效果。BBC的著名全動畫科教節(jié)目《與恐龍同行》就是用mental ray渲染的。逼真的實現(xiàn)了那些神話般的遠古生物。

Mental Ray for Maya 2017的功能
1、高容量三維繪制軟件。使用MentalRay獨立的三維渲染軟件生產(chǎn)出高品質(zhì)、大批量渲染復(fù)雜的電影，電視，和更少的時間設(shè)計可視化項目。
2、Mental Ray瑪雅，3DS馬克斯，Softimage的作品，和3DS MAX軟件，提供與混合應(yīng)用管道工作室的靈活性和簡單性。

更新日志：
Fixed several issues in ExportExactHierarchy. For Viewport and IPR rendering, this mode is enforced since Beta8
in order to provide updates of moved geometry groups and similar scene changes.
Fixed possible camera misalignment between viewport and final frame rendering.
Fixed automatic detection of number of threads used for interactive rendering (Viewport or IPR).
Fixed missing lighting update when moving a group containing light(s).
Fixed possible color clipping artifacts in progressive rendering done with fixed point (8 or 16 bit)framebuffers.
Fixed possible artifacts in scenes with volumetric rendering. Volume was not set correctly if shadowshaders were returning false, which in particular was the case for some Bifrost scenes.Recently added mi_ray_differential_transform function was not exported in the Plugin’s symboltable.
For MILA layering shaders, fixed possible artifacts on thin-walled materials, and scenes withphotons/caustics.
For MDL materials, fixed black rendering artifacts if zero-value volume absorption coefficient was specified.
