Hi all,

I create a bounding box using OBB (Oriented Bounding Box) and it works fine:

But when I update the box position and rotation to match my object’s position and rotation it shifts the bounding box:

What’s curious is that I happen to do the same 90° rotation around the Z axis in Blender before exporting the object.  
In Blender, I select my object in “object mode”, I then press the “R” key, then the “Z” key, then press “90” to apply a 90° rotation and I export a compressed .glb file.

I reproduced the issue here: [Bounding box issue - JSFiddle - Code Playground](https://jsfiddle.net/o401av28/62/)

Thanks for your help 😊

To fix this issue, I simply had to apply the rotation to the object in Blender before exporting, so that its local coordinate system is reset.

Here are the steps in Blender:

1. Select the object in Blender.
2. Press Ctrl/Cmd + A to open the “Apply” menu.
3. Choose “Rotation” from the menu. This will apply the rotation and reset the object’s local coordinate system.
