Hi Mental Ray users and lovers,
over the course of the past 12 months, we have converted most of you, the existing and eligible Mental Ray customers, to a perpetual licensing model. That is giving you plenty of time for finishing current Mental Ray projects and for transitioning to alternative renderers in the coming years.
As some of you have noticed, the NVIDIA Licensing Portal was shut down earlier this month. That means, the option to manage your license tokens and generate license files yourself is not available any longer. We are working on a different solution that will allow you to move Mental Ray to another machine easily. We are going to announce any news here, on this blog.
Please do not hesitate to contact arc-licensing(at)nvidia.com in case of licensing issues or requests.
Happy (and uninterrupted) rendering!
Inside mental ray 
Hello…There are some news for 3ds max User ? for example for 3ds max 2019 or 2020 ?
best regards
Marcello
Hi Marcello. As of today, we have no plans to update Mental Ray for 3ds Max 2019 or beyond.
Mental Ray is the best why stop it instead of improving it ?
Good question! Well, one answer is, that NVIDIA has changed its focus from developing and licensing end-user 3D rendering software that competes in the market to a software and technology platform provider that helps implementing general support for GPUs in any software.
I have been using mentalray for 7 years.Maybe you can consider developing mentalray plugins for other software (such as houdini).I accept mentalray to continue charging
Hi LIU, at the moment, you can use the current Mental Ray without any charges! (except for animations and batch, but time will tell…)
Hi we need new Mental Ray plug in for Maya, how do i get it
Chandra, just download from the links we posted here.
can we use Mental ray 2018 in Maya 2019 ?
Rahul, you can’t use the plugin for Maya 2018 “as is” in Maya 2019, unfortunately. Typically, you need to update an existing plugin for new versions of Maya, for example to take advantage of new features.
Recently reinstalled the operating system, but I did not save a copy of the mentalray license, and the license portal was also closed, I can’t download the license now and activate my mentalray, in this case, where do I need to go Retrieve my license
The NVIDIA Licensing Portal has been closed in the meantime, so you cannot move your license to a new machine yourself any more. Please contact us at arc-licensing(at)nvidia.com for help.
HI steffen, where I can buy mentalray license? I need mentalray license for my 8 render node. i tried here https://store.nvidia.com/store/nvidiamr/en_US/Content/pbPage.mental-ray# but no luck.
You can get licenses for the plugins free-of-charge to finish your Mental Ray projects, just contact arc-licensing(at)nvidia.com. The Mental Ray Standalone is completely free to use nowadays, so can use any number of render nodes / Satellites without additional licenses.
