Problem with loading renderman renderer

[wy.klight]

I am using Maya 2015, and I have successfully install renderman 21 non-commercial version. 

However,I am currently experience some problem when loading renderman.   I am unable to tick the "loaded" box in plugin manager(the tick would disappear once my mouse leave the box). Hence, I am unable to access to the window/panel for renderman.

this is the error that I found from script editor, whenever I tick the "loaded"

// Error: line 1: The specified procedure could not be found.
(RenderMan_for_Maya) //
// Error: line 1: Unable to dynamically load : C:/Program Files/Pixar/RenderManForMaya-21.2-maya2015/plug-ins/RenderMan_for_Maya.mll
The specified procedure could not be found.

Is there anyway to fix it?

Hello @wy.klight,

Sorry for the inconvenience. I understand you can not find your Renderman plug-in in Maya. 

Make sure the specs match up with your Maya version 

1. Clarify the exact version of Maya, for example: Maya 2013 (Gold), Maya 2013 SP1, Maya 2013 SP2, Maya 2013 Extension 1 or Maya 2013 Extension 

2. The Extension versions are completely different from the Gold and SP version.  The Renderman plug-in must be re-compiled correctly to a particular version of Maya.

3. You will need to tell Pixar the version of Maya you are using and confirm the Plug-in is compiled correctly against the Gold, SP or Extension version of Maya 2013.

Please keep us posted on the progress.

Hello @wy.klight,

You may also be experiencing an issue with an incomplete install of the plug-in maybe RenderMan didn’t go through.

Please check to see if you have the following file C:/Program Files/Pixar/RenderManForMaya-21.2-maya2015/plug-ins/RenderMan_for_Maya.mll, if not...

Please try to conduct a Clean Uninstall of the program use MSfixitTool to complete the uninstall & Download via the  Autodesk Virtual Agent. 

Let us know how it goes.

Hello,

I am using Maya 2018 student version and Renderman 23.0.  I was working on a personal project this morning and everything was going smoothly.  This is not a new file, I have been working with it for quite some time now and never had this sort of situation before.  I then saved and quit the file.  When I came back to it, I began running into a whole mess of issues.  I am having the same issue as in this thread, where the Renderman plugins cannot be clicked on to load and no matter the file, it will crash when I attempt to run IT render.  Below is a brief example of the error I have received.  As you can see, I even tried downloading the latest version of Renderman (23.1) which has still not resolved the issue.

Error: [rfm] ERROR: (MainThread) RenderMan_for_Maya initializePlugin: Failed to register geometric override: PxrRodLightFilter //
// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/startup/autoLoadPlugin.mel line 35: RuntimeError: file C:/Program Files/Pixar/RenderManForMaya-23.1/plug-ins/RenderMan_for_Maya.py line 905: (kInvalidParameter): Cannot find item of required type //
// Warning: file: C:/Program Files/Autodesk/Maya2018/scripts/startup/autoLoadPlugin.mel line 35: Failed to call script initialize function //
// Error: file: C:/Program Files/Autodesk/Maya2018/scripts/startup/autoLoadPlugin.mel line 35: (RenderMan_for_Maya) //

Any assistance that can be provided would be greatly appreciated.

Thank you,

I am having a similar issue....Maya crashes when trying to render. 

I tried to the clean uninstall for renderman and the error continues.

Hi Claudio,

I asked a friend and it turns out that it has to do with the licensing.  You may have multiple licenses and need to delete them.  Renderman may be looking at the old files and update the date but not update the Mac address or host name if you have recently updated your computer.

Under Program Files > Pixar you should have one pixar.license file.

If you see something that looks like this.  Try deleting them all, uninstalling renderman again if you re-installed it, and downloading it one more time.

Let me know if this works for you!  Best of luck!

Hi Nicholas,

I did exactly as you mentioned, removed the files ( I had 2 licenses), uninstall render man, than download again from renderman official site. I did the process two times, but still have maya crashing: After setting the scene (geo + pxrsurface + pxrdomelight ), hit render, It window pops up, full white screen, followed by the message "it.exe is

notworking" , than Maya crash.
