Thanks for your answer.
I added the sockets, but how do I tell my grip to use them? “Requests Socketing” did not do the trick. And can i define the overlap radius of the socket?
EDIT:
I just checked what socketing does on the example map with the gun. Thats not quite what I want. When you pick up the gun, the handle is socketed to the hand, ok.
But what I want is, that you cant event pick up an object at one side. I have a needle, which is supposed to only be gripped at the “knob”
