I looking at dagger stabbing. With grippable skeletal mesh no issue grasping dagger with ‘interacts with physics’. When dagger stabs target want it to penetrate target up to the hilt and then allowed to be drawn out (with some level of fiction). I tried using a physics actor to join the hit target to tip of the dagger and allows me to restrict the flow of the dagger along the blade but really not a complete solution. I see we could implement a custom grip. Would is the best approach or am I missing something?
