we have created a new build of the NVIDIA Mental Ray for Maya plugin, version 1.2.1. The primary purpose of this update is to fix a problem with the original installer, which stopped working with latest NVIDIA driver installers on Windows. At the same time, we also addressed few minor issues in the plugin itself, and in the Mental Ray core engine.
You can download the new version from our Mental Ray for Maya Forum for Linux, Windows, and Mac. This update is not auto-distributed through the NVIDIA Professional Application Center this time.
We would appreciate if you let us know that it works for you.
we got several reports that the installation of the Mental Ray products on Windows systems may fail, or may not start at all. It turns out, that this happens when the latest NVIDIA drivers (version >390) have just been installed before the plugin.
The reason is: the NVIDIA installer framework keeps some files on the system, in order to speed up subsequent installations, and to retain a history. The latest installer version coming with the most recent drivers is not compatible with the older Mental Ray installer version, unfortunately. We are working on a fix. For a quick workaround, please visit our forum post Mental Ray Installation Fails.
Sorry for the inconvenience, and Thank You for your patience.
For all users and lovers of mentalray and Mental Ray (as we used to call it lately),
in case you did not notice, I have sad news: we stopped selling NVIDIA Mental Ray and the related Autodesk Maya and 3ds Max plugins end of last year. For details see Mental Ray and Iray product updates.
Fortunately, those of you who purchased licenses from us, don’t worry, you can continue to use your Mental Ray product for as long as you wish. You are eligible to convert your licenses to perpetual, just contact us by email as mentioned in the FAQ above. The same is true for schools and institutions who have registered in our Mental Ray EDU program. It’s worth to note, that the perpetual licenses are free-of-charge, and therefore do not include any support.
Even if you happen to have no license, you can still freely use the Mental Ray plugins for interactive rendering in Maya and 3ds Max, like with Maya IPR and 3ds Max ActiveShade, as well as for rendering final quality still frames in Maya’s Render View and in the Rendered Frame Window of 3ds Max.
The plugins are essential if you want to load legacy mentalray scenes in recent Maya 2017/2018 or 3ds Max 2018, to render them, or to convert them to an alternative engine, at least. But more generally, you may use Mental Ray to learn all the fundamental rendering and lighting techniques like ray tracing, global illumination, image-based lighting and much more, from the software that was/is the defining standard for a lot of these features. The plugins offer the full functionality of Mental Ray no matter if you have a license or not.
To unlock rendering of animations with Maya Batch or Backburner or Mental Ray Standalone, you need a license. We are open to giving out licenses to cover your critical and ongoing Mental Ray projects. Just let us know.
You can find the download links of the latest versions in our forum at
NVIDIA ARC Forum – Mental Ray for Maya and
