10108	Make GLTF output so that importing into Blender sets the center of rotation at center of scene	u34216@…	Tom Goddard	"{{{
The following bug report has been submitted:
Platform:        Windows-10-10.0.19045
ChimeraX Version: 1.6.1 (2023-05-09 17:57:07 UTC)
Description
When Exporting as GLTF with default settings (so centering enabled) the centering does not work properly. The ""centering"" objects gets the (mostly non zero) position of the 3D structure and the structure gets the position set to 0/0/0. It should be the other way around to create a proper centering of the pivot point.
I created a little video to show what is going on:
https://www.youtube.com/watch?v=QLPA_oTZDUw

I tested multiple Files with different 3D Programs and the Unity Game Engine. So it's probably the mentioned swapped X/Y/Z Position.

A non zero pivot point makes working with the 3D Model really annoying and the ""centering = true"" should probably create a properly centered pivot point.
