Mixamo animation not working for Unity

I’m having a problem trying to add the animation to the character model. I keep getting this message when I try to set the animation rig to copy from other avatar I get this error message: copied Avatar Rig Configuration mis-match. Transform hierarchy does not match: Transform ‘Hips’ for human bone ‘Hips’ not found

This is before I click apply.

And this is after I click apply.


When I do that the animation is gone for some reason.

Model 1: You have probably created an Avatar for a model. It means that the Avatar you created has the Bone or Transform Hierarchy According to that Model. It means that if that model has a left arm having the name Left_Arm, then this name would be assigned to the left arm bone of the Avatar. And all of the model bones’ will be assigned respectively.
Model 2: Now, You have another model that has the same Avatar assigned to it that was assigned to the previous one. Keep in mind, that Avatar has some bones assigned to it. And these bones are from the previous model. But you have assigned it to another model. So now the bones of the Avatar are not matched to this model.
Solution 1: You can simply just create another avatar for this model rather than copying from another one.
Solution 2: Another thing you can do is manually assign each bone of your model to this avatar. But again this will lead to problems for the previous model as the hierarchy will not match. Solution 1 is more useful.
