When you load a glTF, the bone transformations are reflected by transformation nodes, and it is these that are important (they are the ones that are updated by an animation, for example). With each frame, these transformations are copied into the bone transformations. This is why updating the bone transformations does not work; instead, you must update the transformation node. You can find the transformation node linked to a bone by doing bone.getTransformNode().
