Destructible part of actor ue4

I have a wall actor or another mesh or blueprints. That i have placed in the game. I want to break the part of the wall or another meshes that is collided with my actor. as i have a long wall if my player hit it by side then break wall from side if it hit it below middle then break that part and disappear that part not the complete wall. the destructible plugin smash the whole part.

hey there !
try to adjust your DM properties . like the hierarchy depth . it s made to simulate depth in damage. you can adjust it so that a part of the mesh don t take damage. but it depends on your fracture too
