How do i bend a cube in UE?

Hello everyone, do you know how i can bend a cube in UE?
Is there any modifier or something?

You can try to do something via shaders, other then pixels they also let you alter vertices.

Note cube is very simple shape and altering vertices positions will only alter existing triangles in mesh, you need to use tessellation in ot the mix to add triangles needed to bend the shape:

Also everything you do in material/shader happens only in GPU and CPU does not follow it, so if you bend shape outside of original bounding box generated by CPU it will be occluded once counding box is out of camera and you shape will disaaper on edges of screen. So you need to set bigger bounding box in such case.
