Hello everyone, I am trying to import render materials from the materailx library in freecad using the GPUOpen Materail Library in the render workbench for my project. but it is giving me this error message. "12:17:53 [Render][MaterialX] Traceback (most recent call last):

Please can anyone helps solve this.

Hello,
Can you please precise OS, Python version, Render version, FreeCAD version etc.?
And also provide full Render start trace (in report view), including log level messages?
Thank you very much!

But I have read from the help page of the render workbench that materialx neds to be install in the system. I am trying to do so but without success.

But I have read from the help page of the render workbench that materialx neds to be install in the system.

No, MaterialX should be directly installed by Render (there should be a message like "[Render][Init] Checking package 'materialx' - OK" at initialization).
I would need the start log to help you further: can you please activate log messages report (in Preferences), restart FreeCAD, activate Render workbench, and copy/paste here the whole Report view content?
Can you also provide the requested information:
Python version (major/minor)
FreeCAD version
Render version
Thank you!

But for the Major and Minor, I do not understand what you mean.
pop os version 22.04

Thank you. There are good news and bad news. Good news: last run has installed MaterialX, it's visible in the trace. Bad news: there is another error while importing the material. Could you please give me the url of the material you try to import, in order for me to make some test on my side?
(major/minor: in Python version 3.10, major=3, minor=10...)

Well, I suspect an OpenGL / GPU issue.
Could you please try to deactivate temporarily your GPU and retry (maybe with this link: https://support.system76.com/articles/g ... witch-pop/ - sorry, I don't really know your distro)? It is a derivative of both Ubuntu and Debian. it resembles both in functionality.
