MentalRay dll not loading-MAX17

[mfeldhaus]

When opening an existing Max16 file (with mental ray as render) in 17, I get missing dll errors for mental ray.  The path in 17 is set to the location where the files are located, but they don't to load.

Obviuosly I can not select mental ray as the render in 17. So I have been playing with ART but not getting the same results as MR gives.  I need to stay with MR to finish current projects.  More time spent with ART and adjusting settings might help....we will see.

Thanks.

After I install 3ds max 2017, I can use mental ray.

So you can't render for only one scene or all scenes.

Could you zip and upload one, I'll test it.

Thanks for the offer tony.su.  Not just existing files show the error, but I can start a new file and load my maxstart.max file and receive the error.  (see attached) This file has mentalray set as the renderer, so obviously the error shows.  If I start a new file with a generic setup, no error msg is generated but MentalRay is not listed as an available renderer....neither is Iray.  (see attached) 

The plugin manager shows them as loaded and a valid path.  (see attached)  For whatever reason the dll's are listed as missing. 

Any ideas?

Thanks for your assisstance.

I'm not sure why.

Could you reinstall 3ds max?

And could you tell me what's OS you use?

[mfeldhaus]

I have tried you suggestion to re-installed Max, which has not helped.  I am running Windows 7 sp1.

Thanks.

For some reason, mentalray.dlz wasn't installed.

So could you try to install MentalrayPlug again?

Attchment you can find it.

Hey Tony.

I ran the installer and the same results - see attached. I did a new install and also tried a repair. If I rename the maxstart.max file to say, maxstart1.max so that it doesn't load, max will load without the error msg.  But the iray and mental ray renderers are not available in the setup drop down.  See attached.

Anything else I can try?

Thanks for your help.

Before you reinstall 3ds max, you should uninstall 'NVIDIA mental ray and IRay feature plugins for 3ds max 2017' and 'NVIDIA mental ray and IRay rendering plugins for 3ds max 2017'

And when you install Max, check if you can install mental ray plugins.

[mfeldhaus]

Hi Tony,

I did as you requested and uninstalled Max and the Nvidia plugins.  When running the install on Max I did not see the option to install the Nvidia plugins.  I completed the Max install and then looked at the installed programs - Nvidia MentalRay plugins are installed.  Ran Max and still no MentalRay rendered to select.  I ran the Mental ray standalone installer you sent yesterday, repair and then loaded Max again.  Still can not see mental Ray as an option under Renders.

More ideas to try?

Thanks for your time, let's see if we can't get this thing working.

Ha! a clue.....  🙂  .......after a closer look, what I see installed are the "feature plugins" at 4.26mb, what I am missing is the "rendering plugins" at 228mb.  I don't beleive the rendering plugins have ever been listed as installed, just the "feature".  Can I get an installer for the rendering plugins?

Thanks.

Success!!  That file did the trick.  I will play around and see if all is well, but initially all loads and I can se the MentalRay renderer.

Thank you for your help.

I have the same issue. Mental Ray didn't install and it doesn't show up in the configuration list after a reinstall. I'll try the Mentalray.rar file you guys have posted here. What happened in the first place though? Why didn't this work the first time I installed it?

[mfeldhaus]

joelgray,

Let us know if it works.

[joelgray]

Yes, it did work. Thank you. I'm still puzzled why Mental Ray was not an option in the installer and the files weren't part of the download. I spent many hours looking online for an answer to this issue. I guess I should have started here first.

Thanks again.

Hi Joel,

Great.  I was thinking I was the only one having the issue, so I am glad to hear it works for you too.

Have a great day.

Where you guys got the install installation package? I'm curious. Because the file I gave was copied from installation package I had dowdloaded.
