I have been a bit confused lately about the issue of updating the gravity of the child nodes of the gltf model in cesium. Recently, when using the gltf model to simulate real-life scenarios, I have always encountered similar problems. For example, when dealing with the hook problem of a truck crane, the hook always moves downwards in the direction of gravity, but always changes with the parent node during the simulation process. I tried to change the rotation and translation of nodes, and I thought changing this attribute would achieve the desired effect, but in reality, I think this requirement is necessary. Is there a good way to solve my needs.
