Problems saving model avatar

Hi there, I recently moved to Unity 5 engine, I'm not new in this world but I am with Unity. I was testing animations on 3d models. I have animations for humanoid bodies that I wanted to apply to a random humanoid model I downloaded.

I select the model in the assets then I select "Rig" --> "Animation Type: Humanoid" (creating from that model) and then I hit configure.

Then the avatar editor opens. The problem is that the model doesnt come with preset for bone position or anything so I have to make them manually. I can make them in that scene, and it will show the skeleton and all the avatar green and ready to go. Then I hit apply and then done. The screen comes back to the main scene but the avatar didn't save the changes.

I think its because I'm adding the transform positions for each bone in a "Clone" model in the avatar editor scene so they won't save for my model and thus the avatar will be reset.

Now, is there a way to make it save somehow in the model? I also tried to make a prefab of the model with the transform in it but Unity does not recognize it as a model so I dont have the option to map the transforms to the avatar.

Thanks in advance.

 

This is pretty old, so sorry for necroing, but did you ever find a solution to this issue? I have a rather.. strange thing I am trying to do and being able to edit the avatar would make my life really much easier.

 

Yeah it's 2022 and now I'm having the same issue

 

Add on another year. I thought it was because of the laptop I'm using (I am very aware Unity runs like ass on a laptop), but it seems like it's not just the laptop.
