I noticed that csg leads to different results if you cut a bjs mesh like meshBuilder.CreateBox and if you cut an imported gltf mesh.
You can see this here: https://playground.babylonjs.com/#C4B8QB#49
It seems to have something to do with rightHandedSystem. Turning it off changes the behavior but there is still a difference between both boxes.
Any idea how to solve this? The imported mesh should behave the same way like the bjs one.
