Greetings. I downloaded the character animation from mixamo. Since the 3D model has a .vrm type, I had to export the prefab from Unity via the FBX Exporter, upload it to mixamo and select the animation and download it. On a 3D model, only the Generic animation type works, if you use Humanoid, it does not play correctly.
Perhaps this is due to the type of 3D model .vrm.
I wrote a small script for the 3D model that makes the character аollow the camera with eyes, head and partly spine. If you turn off the Animator and start the game, the 3D model will stand in a T-pose and follow the camera with its eyes, head and back, and if you turn on the animator, it will only work on the eyes. During the animation, I can change the offset position of different parts of the body (back, neck, head), but I can not rotate.
In the video, if you look closely, you can see how the eyes flicker/shake, that means the animator is trying all the time to return them to their original position.
How can rotation offset be given to different parts of the body so that they do not conflict with the animator?
