How to add more triangles to a plane in UE4? Help!

Hey I’m wondering if you could help with me with UE4, It isn’t much and it probably an easy answer. How do I add more triangles / subdivisions to a plane in UE4? For example my rock is a perfect sphere and I want more displacement and geometry. On Blender it is a simple right click of the mouse and press “Subdivide”. But how do I do that in UE4?

Thanks.

Just enable tessellation in the material, it automatically adds more geometry…
