how can i map the generated bones to MIXAMO-format bones

[mapledky]

Great job!
As i can see the generated bones are named with number (bone_0,bone_1...),I wonder whether theirs a mapping relationship between number and the standard MIXAMO-format naming(MIXAMO-hip....)?
Thanks again.

I think the only bone that always gets the same number is the pelvis. It does the spine first and from there I just use the world axis to get left/right up/down. I used a loaded mixamo skeleton as a reference. There are probably better ways to do it.

I have the same question.

I soved this problem by mapping the bone's number directly to the mapping file provided in https://github.com/VAST-AI-Research/UniRig/blob/main/configs/skeleton/mixamo.yaml.

Hey @mapledky

Curious how you solved this... did you build a tool outside UniRig to rename the bones, or did you tweak the code to output Mixamo-compatible names?

Would really appreciate any details or tips on your approach.

Thanks in advance!

I made lists of leaf and "root" bones to make a list of connected chains. From there I programmatically try to figure out what the chain is, then name the bones. Unfortunately directly mapping the default names does not work, as they are never in any guaranteed order.
