IsADirectoryError: [Errno 21] when importing MDL

[othello777]

Hi, I'm trying to import the V1 model from /home/othello7/Documents/Ultrakill_SFM/models/ultrakill/v1.mdl
V1 model: https://nitter.net/ULTRAKILLGame/status/1276646762539896837

but I get this error:

Everything is the latest update.

Imported fine for me. I need more time to investigate

[othello777]

My system specs in case it's helpful:

Linux Mint upgraded to 22.10 packages
blender 3.3.1 downloaded from the blender website
Sourceio 4.0.3

and there are several layers of symbolic links in the path to the file.

I am personally getting an identical error from what I can tell, every source model .mdl I've tried to import thus far end up in the same IsADirectoryError.
As a sidenote, an excplicit install of Python 3.8 was required to enable the plug-in after installation, otherwise a missing dependency of py3.8 libs would occur. Probably has nothing to do with anything in this particular error, but may be worth mentioning just in case.
This was tested on Arch Linux with the latest Blender 3.3.1 from the official package repo alongside 4.0.3 of SourceIO. An attempt on the windows partition might be in order to check for the potential of an OS anomaly.

I've made an attempt to fix it. Try with version from master

And it it crash again, provide full console log

Ace fixing mate, top marks! Loading in the same models from before now works a charm! Sorry to say however that the next step of loading in the textures for said models leads to a somewhat similar error. Unfortunately I cannot tell at a glance whether this is user error or not.

Many thanks for what you've done thus far though! 💯

It's weird to see stack trace to system python instead of blender bundled

@othello777 please take a look at #156 and #88 you can find solution to your problem there
