    Default Mental Ray renders only black screen

    I am unable to get Mental Ray working properly in Maya 2016. I'm trying to use it to render FumeFX simulations. When I try to render a scene (ANY scene, not just while using FumeFX), it renders a black screen.

    I was able to get Mental Ray working by installing Maya 2016 Ext. 2, but Fume is not supported in Ext. 2.

    I tried uninstalling Maya 2016 and re-installing it. I also removed and re-installed Mental Ray, and I installed service pack 6, as well. Others have suggested that I may not have the right version of Maya or mental ray, but I'm not sure how to check that.

    Can anyone please help me figure this out? Thanks in advance!

    The version information should be in About, or Help. I can't remember which as it moved at one version.

    Anyway, when mental ray is loaded it also tells you in the Output window.

    Thanks! The version that shows in Help says this:

    Version: Autodesk Maya 2016 SP6
    Cut ID: 201603180400-990260

    How do I check my version of mental ray? When I load it using the plugin manager, I get a big text spew:

    Well it does seem to be looking in mentalrayForMaya2016 which is the right place for the 2016 version of the plugin. But not being able to load mayabase.dll is an issue.

    A couple of things to check.

    Did you install the mentalrayForMaya2016 SP6 update?

    Had you uninstalled the mentalrayForMaya2016 plugin and re-installed it from scratch?

    Was that the report in the Script Editor or the Output Window? Check just the top lines of both for mrfm version information.

    I don't think I installed the mentalrayForMaya2016 SP6 update. Where do I find that?

    I did uninstall mental ray and re-install it from scratch.

    Thanks!

    you do need the SP6 for mental ray for Maya 2016, too. It should be in the same location you found the SP6 for Maya 2016.

    I upgraded to Maya 2016 Ext. 2 with SP1, and that fixed it. I had SP6, and the latest version of mental ray.... It must have been some mismatch somewhere.

    Thanks!
