How can use realtime Smooth Corner on UE4?

I’d like to achieve the function called Smooth Corner and Rounded Edges, etc. on UE. Before I say that you form a thin polygon into an edge boundary of a polygon and a polygon automatically, this is the function given in a topic for discussion by this forum.

An advantage of Rounded Edges is to be able to show the resource made for the old generation machines richly in minimum time.

Engine “Mizuchi” made in Japanese silicon studio then, this function seems mounted, what kind of procedure is needed to achieve this in UE4?
