mixamo.py issues

[moadib]

I just tried it with YBot character from Mixamo site on ue 4.17 and _rooted version have visible artifacts. Some spherical joints are missed and some vertices messed up.

Also, i think that "required_bones" should contain all bones from old skeleton, not only from bone_map.

Hi can you post the animation file and a screenshot ?

Thanks for reporting, the problem was caused by ybot having multiple sections. I have updated the script and updated the tutorial with a special note with your credits:

Thanks! Mesh geometry converted without issues now. But there is some difference in bones hierarchy (same YBot from mixamo that i posted earlier).

Bones without vertices attached placed correctly in hierarchy, but without icon and not displayed in viewport.

Original model:

Fixed by script:

If my assumptions are correct - "required bones" in converted model must contains all "required bones" from old plus "root". Not only from new_bone_map.

I have updated the script a bit.

Basically active_bones are the ones mapped to one or more vertices (in the old script it was the required_bones list). So i have changed the code to dynamically build the active_list, and to mark as required_bones all of the single bone of the Skeleton.
