Objects hierarchy already exist at Blender. Also Blender have more possibility to control objects settings and materials, thus I choose to prepare GLB models at Bledner, not at PlayCanvasEditor. At least for now.
Thus at this topic I’m asking not about PCEditor, but about PCEngine - which of 2 methods from 1 my message at this topic are better to use with your PCEngine?
In which case, it be “Make all objects at 1 GLB model, found needed by object-group name, control it;” for me. As you are not using the Editor, there doesn’t seem to be a net benefit using separate GLB files
