Three.js: draw bounding box around skinnedMesh

问题

I'm trying to draw a boundingbox around a skinned model:

const box = new THREE.BoxHelper(trooper, 0xff0000);
scene.add(box);

https://jsfiddle.net/66sor15y/4/

As you see the model doesn't fit the bounding box. I filed an issue to understand the problem, but I still have issues drawing the actual box.

Any help would be highly appreciated!
