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:

bpy.ops.object.select_all(action='SELECT')
bpy.ops.object.delete(use_global=False)
Deleted 3 object(s)
bpy.context.space_data.recent_folders_active = 0
bpy.ops.object.add(type='ARMATURE', enter_editmode=True, align='WORLD', location=(0, 0, 0))
bpy.ops.object.editmode_toggle()
Traceback (most recent call last):

Thank you in advance!
