mental ray for Maya 2015 SP4

mental ray for Maya 2015 SP4 is now available for download. It ships with mental ray version 3.12.1.18.


These are the most important fixes:

  • We are glad to announce that we were able to remove the cause for freezes and crashes on Mac OS X version 10.9, “Mavericks”.   To our Mac OS X users, test it out and let us know your experiences.
  • Some problems around motion blur of XGen geometry were fixed. Please, note that we still recommend setting the Motion Steps parameter to 1 when using XGen hair with motion blur (see mental ray Motion Blur Settings in the XGen Preview/Output window) . This issue will be fixed in the future.XGenMotionSteps
  • Artifacts with texture caching of Tiff textures as well as a problem with imf_copy and multiple level support were fixed.
