UE4 - Highlighting the cross section of intersecting geometry

I looked through the tutorials and they don’t really get into any depth as far as the implementation goes, which is what I’m still trying to learn.

I suppose a way I could accomplish it would be to do two render passes, one where the object renders normally, and one where the object renders only when occluded. Then take the two render passes and cull everything other than where they intersect. Though like I said, I’m not familiar enough with shader creation to know what I’d need to be able to do this.
