Hi, I am making KKBP 7.0.0 compatible for Blender 4.2 LTS Beta. Can you try it on that version instead? I am not seeing any import errors in that version.

[StShAzzy]

i'll try it soon

[StShAzzy]

ok, so now Chika Haruko works, but it seems there's a specific eyebrow that causes the process to fail

          Make sure the default model imports correctly before troubleshooting on this model!

seems the problem is a eyebrow? i'll try narrowing down the possible causes

[StShAzzy]
