Hype Project: DoorSwing.zip (56.2 KB)
If so please note that there is no 3D effect in Hype so the door as it swings shows no thickness.
Settings in "Metrics Inspector" with the "Door Swing" group open:
Transform Origin: "X" offset is 100% - i.e. at the far right side of the group.
When the door is closed the "Y" angle rotation is "0".
