I have generated an animated character in mixamo. I downloaded the FBX and converted it to glb (using Blender). I had to adjust the scaling from 0.01 to 0.23 so that it is visible when used in a cesium.js map.
Now there is one problem: When I click on the 3d model, the square marker for the tracked entity is not centered on the model, it is offset two to three times the diameter of the model.
This does not happen consistently with all glb files, just the ones that I created from fbx files downloaded from mixamo.
I have checked the "Origin" of the model, it seems to be sitting right in the center between the feet, so that should be ok.
Any suggestions?
