I created it according to the Joint Tool tutorial with the name Global, then created a group called Global and tried to upload everything to the editor. The result is the same (the artifact doesn't rotate).
As I see it, but this is not certain, you need to do the following: - Create a bone (with any name, even "Petrushka"), attach the model-mesh to it, and then there are several options, choose one of the following:
a) Create an additional bone named GLOBAL and link the bone responsible for the model's animation to it.
b) Create a "HELPER" (Dummy or Point) with the name GLOBAL and link the bone responsible for the model's animation to it.
c) Combine the bone responsible for the model's animation and the model itself into a group with the name GLOBAL.
The main thing is that there should be no identical names, because during export, a dilemma will arise as to what will be the main one.
