Hello, I am trying to load the most recent version of Vray in Maya 2023 from the zip. I am editing my maya.env file, I have attached a screenshot of the code.
I can load the Vray plugin in Maya - but it crashes every time I add simple objects and try to edit attributes. It’s incredibly unstable. Is anyone else having issue loading Vray from zip in Maya 2023 - or is there something wrong with my .env file?
Thank you in advance -
Kevin
At first glance, I noticed the VRAY_PLUGINS variable is missing. There’s a pretty detailed explanation as to how to install from zips here. Have you checked everything?
Thanks for your reply! The VRAY_PLUGINS variable is only necessary if you want to run Vray Standalone, I believe. Do I need standalone to load from zip? I don’t think I’ve had to do that in previous versions of Vray/Maya
Okay. I managed to reproduce it when using a Maya.env file to drive the variables. I’m not sure if this is intended - I’ll check this and get back to you. Otherwise, the current setup is to set those variables in the System variables (System Properties>Environment Variables) as described in the docs page I linked in the previous post.
EDIT: Okay, there shouldn’t be any issues. I’ll test some more and write back.
There seems to be some issue with setting environment variables through Maya.env, since setting them regularly through Windows works as expected. For now, I suggest you do it this way.
EDIT: Logged (internal bug-tracker id: VMAYA-11483).
We found what causes the issue. Declarations of environment variables through the Maya.env file will extend existing variables, rather than overwriting them. For example, the %PYTHONPATH% part is usually written as a way to extend variables and since Maya does this already that part stays as it is and causes problems. Your Maya.env file should look like this:
VRAY_ZIP_ROOT=c:\vray_builds\vray_52002_maya2023
MAYA_RENDER_DESC_PATH=%VRAY_ZIP_ROOT%\maya_vray\rendererDesc
VRAY_FOR_MAYA2023_MAIN=%VRAY_ZIP_ROOT%\maya_vray

We’ll fix the documentation page as well.
