    Hi everyone!

    I am trying to apply an existing humanoid avatar to imported humanoid animation. The rig for the animation and the existing avatar are exactly the same. When I try to define the avatar for the imported animation as 'Copy From Other Avatar' and then select the existing avatar, I get this error of Bone Lengths not matching.


    If anyone knows how I can solve this error or where I can find more information about what's causing this error I would greatly appreciate it! Thank you in advance!

    I found a solution for me for this problem. (I changed the positon of the bones a bit in Blender - Edit Mode)

    In Unity choose the Blender file. Open the 'Rig' tab, change 'Animation Type' to 'None'. -> Apply
    Then change 'Animation Type' back to 'Humanoid'. -> Apply
    So the messages are gone and the animation bones are correct.

    Hope this helps.

    I am having the same issue as OP and that did not fix it for me. These bone length warnings would not be a big deal for me except that I think they are screwing up the root motion on my animation. Nobody knows what this warning means or how to fix it?
