@zicklag I share the point of view of @MagicLord here How to make a simple robot gripper? and this answer to my question, that is we don’t need to make a step in Blender Pose Mode if there is a real time possibility in Armory.
Actually (but can change), what seems to me to be not often clear in Armory for the moment is the frontier between things to do in Blender or not, in the sense of reusable or not in Armory.
