V-Ray 5 update 1 for Maya 2020 unable to load plugin

[rkoonce]

I'm getting this error on both 5.1 & 5.1.1:

// Error: file: C:/Program Files/Autodesk/Maya2020/scripts/others/pluginWin.mel line 317: Unable to dynamically load : C:/Program Files/Autodesk/Maya2020/vray/plug-ins/vrayformaya.mll
The specified procedure could not be found.
//
// Error: file: C:/Program Files/Autodesk/Maya2020/scripts/others/pluginWin.mel line 317: The specified procedure could not be found.
(vrayformaya) //

I've done clean uninstall/reinstall multiple times, logged out & rebooted.

I can revert back to V-Ray 5 hotfix 2 no problem.


I know there are a few similar topics from a few months ago but I've seen no definitive solution posted.

Hello,
With 5.1 we've made the V-Ray for Maya installation more self-contained which moved some dlls around and it seems one or more of them cannot be found. The new layout makes use of Maya's module files to set up the PATH env variable. Please check if you have a VRayForMaya.module file in C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2020 . It is a text file and should contain the lines:

PATH+:=bin\hostbin
PATH+:=bin

If one is missing, you can add it (but mind the order!), or you can uninstall V-Ray for Maya, make sure the module file is deleted as well and then reinstall V-Ray for Maya.

Also check if you have a stale VRayForMaya.module file in another location and delete them if so, you can see all module paths by running "getenv MAYA_MODULE_PATH" from Maya's script editor.
If you are using ZIP install, also check that you've updated your env variables according to the updated instructions on our documentation page: https://docs.chaosgroup.com/display/...ation+from+zip

Hi,

I have exactly the same error message. Both in maya 2020 and 2022 .
I have the proper module in the module folder C:\Program Files\Common Files\Autodesk Shared\Modules\Maya\2020
It also contains the proper paths:

PATH+:=bin/hostbin
PATH+:=bin

It must be related to some ENV path is my guess - but I can´t find the source of the problem.

windows 10
vray 5

desperately need to get this working.

any help appreciated!

I've tried placing the module file in all the various locations listed by "getenv MAYA_MODULE_PATH" but V-Ray 5.1/5.1.1 refuses to load in either Maya 2020 or 2022.

And I have lost count of how many times I have uninstalled/reinstalled.



My team would really like to take advantage of some of the new 5.1 features & this is holding us back.

If anyone has found a reliable workaround I would really appreciate it!

Latest update 5.10.22 from 9-30-21 has fixed this issue for me.
