Doesnt work in blender 4.1

[Fennecai]

Describe the bug
due to the removal of the auto smoothing feature in blender 4.1, in favor of a modifier that does the same thing (smooth by angle modifier), this addon no longer works on model importing.

To Reproduce
Steps to reproduce the behavior:

1. import a vmf or model in blender 4.1
2. see the errors

Expected behavior
i expected the models/vmf to import correctly, but they dont import at all.

Related files
it does this with any mdl or vmf containing models, so...

Ah, so that's why it's doing that. I was getting the error myself but I was not sure on the cause of it. Thankfully you have discovered it though, hope to see this fixed eventually.

I fixed it by editing the script on my end. my fix maybe isnt up to the best coding practices since i have very little experience in python (just in other languages) but it works without any issues.

i dont know how pull requests work or even what they are really, so if anybody wants my patch before the addon is patched officially, here is my modified version of plumber/asset/model.py
