Using an override controller instead of directly using an animator controller on the gesture layer breaks the sdk builder window, preventing you from uploading due to the layer mask check in the code only being made for animator controllers, the moment you use an override controller it breaks code wise and spams errors.
Reproduce:
Simply use an override controller on the gesture layer instead of an animator controller.
Would be nice if this could get fixed in the sdk because using override controllers would allow people the preconfigure animator controllers and allow people to override stuff similiar to the old way in SDK2.
Meaning they dont have to dive in and learn animator controllers.
Note: Using an animator override instead of controller works on every other layer, tested this ingame. I'd guess it works for gesture too, but cant test due to sdk breaking.
