AttributeError: 'Mesh' object has no attribute 'show_double_sided'

Hi!
I'm trying to import a IQM model using iqm_import.py, but I'm getting an error saying:

AttributeError: 'Mesh' object has no attribute 'show_double_sided'

So, it imports the armature but not the mesh!
I'm using Blender 2.83

Here is the full Blender Info Log:

Thank you in advance!

I'm not surprised the importer has finally broken! It's been a couple of years since it was written, and I have not kept up with the new Blender changes....

I understand that new versions can broke the plugins, but I tried with previous versions and I got the same error...
for example, it says iqe_import.py has support for Blender 2.8, so I tryed the 2.80 version and it didn't worked..

Thank you for your attention!

It's been a solid year, but I'm new to using this tool, and after taking a look at Blender's API, replacing 'show_double_sided' with 'use_mirror_topology' fixed the issue. Hopefully this helps anyone who's trying to import IQM models in the future!

Yeah, replacing this line (655 from iqe_import.py) to mesh.use_mirror_topology = False
Worked for me, too.

asstools/iqe_import.py

Line 655 in 0c52fe1

mesh.show_double_sided = False
