"AttributeError: 'Bone' object has no attribute 'select'" when Prep for target application

Vind commented

2025-12-05 20:35:35 +00:00

I'm familiar with the prior version but decided to try version 9. I installed Blender 5, the latest MMD tools, the v9 importer into blender and the v5 exporter into KK sunshine.
I exported new model files from KK sunshine.
I imported the new model files with the button "Use FK Armature"
I then immediately pressed the button "Prep for target application"

I get the error: AttributeError: 'Bone' object has no attribute 'select'

Full log below. I tried this on two two different models and got the same error. They both work in the prior version.

Thanks for all your work on this project!

Hi, thanks for fixing the issue! Unfortunately, as it's merging the bones it gets a new issue. I tried on two different models, and on both it gets an error when:
Merging bone: cf_hit_spine01

Full log attached.
