Destructible Mesh Health and Visual Break Down

Hey all!

Im brand new to UE4. I have been tinkering with this and that and I came across the art of destructibles. I want to have it take several hits before it shatters. And, if possible, make it visually crack as the health gets low before breaking. Do I just set up a class blueprint variable that records the health count on the mesh? And is it possible to make the mesh look cracked?
