Create character -> IndexError: list index out of range

[jaggzh]

I have one sort-of-finalized character (1.7.7 was erroring on finalize).
When creating a new character, with 1.7.8, I get:

  File "/home/jaggz/.config/blender/2.91/scripts/addons/MB-Lab/__init__.py", line 2492, in execute

Does character creation on empty scene works well? If yes, can you please send a blend file with the "offending" character only?

[jaggzh]

Hi, thanks a lot.
Okay, so a fresh blend lets me create one or more characters.
To reproduce the error with this .blend:
https://pasteall.org/blend/5b98b8dc5b6c4b59913bd63c69df0ff5

1. Load (accept or ignore the driver execution -- it's just a python adjustment of text objects)
2. Finalize current char ("Finalize with textures and backup" button), accepting the automatic .png name
3. After finalization is done, click Create Character.

OK here's patch to fix it:

@jaggzh also if you don't want to patch MB-Lab you can just workaround the problem by just deleting all manuellab_* properties from decimated version of the character (f_ca01.001)

[jaggzh]

Thank you! It's good to know the different methods. I can probably handle patching the thing, or just checking it out from github if it's committed. Thanks again, I'll try to try it soon. :)
