Is there a way to sculpt islands like Crytek's sandbox?

In CryEngine you can sculpt land and carve out various land structures. UE4 is box method, which has it’s upsides but it’s way less fun. I wondered if there was a setting I missed or if not at all.

You mean like landscape/terrain tool? If so, unreal has it:

Not exactly what I wanted but I see that is the UE4 equivalent. Thank you for pointing it out to me kind sir!
