My sockets (the one u use to stick a item to like your hand) is grey and when i click on the button to select a socket nothing happens
hi @othertraderguy and welcome!
Im guessing you are using one of the default UE mannequins?
If so you will find some of the sockets (and bones) unavaible for whatever reason.
BUT!! You can add new sockets to any bone you have access to in the skeletal mesh.
