Say I have a human model with attachable costumes. Each model is bind to a skeleton, but the skeleton shares the same structure (just different weights, etc).

So, how do I get around to transform the bone of one to also update the others? No need to be bi-directional. Like modifying the human skeleton will update all costumes’ skeleton (multiple).

One idea is to rebind those meshes/costume to the human’s skeleton. But I janky-ly tried this with no success as the weights are destroyed.

Currently, this is basically what we use: When we select a certain bone type to transform, we create a dummy object with the same transform and transform that dummy instead. Once the transform is done, the new value is copy back to that same bone type on each skeleton.

```javascript
this.transform.addEventListener('objectChange', function (event) {
    for (var i=0;i<target.length;i++) {
        target[i].position.copy(this.dummyGroup.position);
        target[i].rotation.copy(this.dummyGroup.rotation);
        target[i].scale.copy(this.dummyGroup.scale);
    }
}.bind(this))

```

The problem with this is that it’s not inherently linked in the engine like actual parent-child relationship or proper skin-skeleton connection.

So I wonder if there’s a way a bone can reference or link to another bone matrix4, or just rebind a skin to a different skeleton, preserving everything.
