Hey @Metallic_emperor!
So usually we need more info than that, but I think I know how to help you.
You want to get your capsule collider, and when you start your roll, take your capsule collider and use the “Set Collision Response to Channel” node with the Collider as the target, and set Pawn = ignore.
Then after the roll, use another “Set Collision Response to Channel” on your collider and set Pawn = block again.
