polyhavenassets's Issues

Trouble Installing PolyHaven Plugin for Maya

Hello. I was looking at your PolyHaven plugin for Maya on GitHub. Following the installation, I got everything set up as easily as it was written, but I got a couple of errors when clicking the shelf tool. First, I had errors for PySide2 and shiboken2 not being found. I just changed them in your files to PySide6 and shiboken6. I thought it would be fine afterwards, but I'm now getting this error:

Error: PermissionError: file E:\03 Creative/Animation/DCC/Maya/Plugins/PolyHaven\get_path.py line 35: [Errno 13] Permission denied: 'settings.json'

I already made sure the directory was fully accessible, so I'm unsure what to do at this point. My other assumption is that perhaps I just need to work in an earlier version of Maya. I usually work in 2023, but I'm trying out 2025. Do you have any suggestions?

Update: I tried installing it in Maya 2023, reverted the PySide and shiboken imports. I'm stilling getting the same error as above.
