Bones roll but mesh don't

Hello, like in title I’m trying to build character with bones, for example legs. 3 bones connected (foot, lower leg, upper leg) very simple armature :slight_smile: Everything is controlled by IK bone. And when I’m trying to set roll for bones it’s only works for first bone for legs it’s only rolling upper leg. How to set i properly if rolling separate bones don’t work. OK, they roll but mesh don’t.
