When importing Mixamo animated characters into Unity, they come without avatar?

I experienced this problem as well but since no one actually answered the question I'll say what I did to solve it. You are correct that it seems to be a version issue, I fixed it by simply making a ...

In Unity, rotating character spine keep going back to original rotation

Unity 2D rigging parts order

It's really simple, but Unity changed the interface recently so most of the tutorials weren't helpful and I didn't know what keywords to look up. So if you click on the sprite image in the asset ...

Unity3D/AnimationRigging - Rig not a child Transform in the Animator hierarchy

Figured it out. While the rig gameobjects were children of the Animator, they were not siblings of the body mesh & armature. Moving them all into the same gameobject fixed the issue.

Can I add rigging bones to a model imported from Blender inside Unity?

How do I convert 2d character rigging animation to frame by frame sprite animation?

Imported IK Rigged FBX model into Unreal Engine makes the feet point in the wrong direction

This looks like a joint orientation issue. Simply put, the joints in your skeleton need to be orientated the same way (or as close as possible) to the mesh you intend to retarget from - there are ways ...

Why do MMOs use different skeletal rigs when one could easily and cheaply do the job?

That's not all MMOs though. Many MMOs don't have race or gender locked classes (which sounds like what you are complaining about). Though you'll find that the same "equipment" in that case ...

Why are my avatar hands not closed when performing clap animation downloaded from mixamo

Rigging a 2D face on a 3D character

My approach to animating a 2d face would be the same as that to animating a 3d face: By doing it in the 3d modeling program. I would break up the face into multiple polygons and then animate their ...
