Cut existing Collision into Convex hulls.?

Hey,

I’m pretty sure that in UDK, when you imported your simplified collision mesh, the editor would automatically cut up the mesh into convex primitives but would also keep the shape of the original mesh. Did this feature actually exist in UDK? is there anything like this in UE4?
Please note I am not referring to the Auto Convex hull tool. I want something that will cut up the geometry I feed it.

If this isn’t a thing in UE4, does anyone know of a script or plugin for Maya that can do this?

cheers
