How to implement skeletal position animation and why can original position animation also be formed into animation

Couple of things. Please see playground: https://playground.babylonjs.com/#XAV73D#10

N.B. Usually, in a Mixamo rig/skeleton, you want to animate rotation, not position. I changed that. If you nonetheless want to animate position, you probably have to change to “BABYLON.Animation.ANIMATIONTYPE_VECTOR3”

Hello, I changed it to a positional animation, but the animation effect is still a rotated state effect

Oh, I see. This is weird. Is this intentional behaviour (@all)? Does it play the rotation from the animationGroup or so?

Anyway, to stop the rotation, you can do something like https://playground.babylonjs.com/#XAV73D#14

The second parameter of the Animation constructor must be the name of a property, not of a function. If you want to use setAbsolutePosition, I think you will have to make the animation yourself, not using BABYLON.Animation.

If I use the position attribute, all the bones are lost. What is the reason for this

Position is a Vector3, not a quaternion (see line 63):
