How to use UE4 terrains brush in game?

[anonymous_user_86df69d2]

I’m trying to create the brush you see in the editor but during the game.I don’t want to actually create the functionality of the brush just the look as I move my mouse over different terrain. Basically this http://udn.epicgames.com/Three/rsrc/Three/LandscapeEditing/region_selection.jpg but I would obviously change a lot of the look , just looking for a place to start.

Thanks in advance!

A decal would probably be the best starting point. Add some mouse-to-world position logic, and you should have something useful.
