NVidia is to EOL Mental Ray. In a newsletter announcing the decision they say that from November 20th 2017 “NVIDIA will no longer offer new subscriptions to the Mental Ray plugins for Maya and 3ds Max, as well as Mental Ray standalone.

Nvidia attributes the reason for retiring the seminal renderer as a change in focus. Under the question “Why is Mental Ray being discontinued” they will that “NVidia will focus on bringing GPU accelerated ray tracing technology to every rendering product out there”, listing OptiX, MDL, IndeX, and IRay for CAD as technologies that will benefit from further investment.
