Hi SlinkyMuffins, no you cannot deform the standard ue4 landscape with this plugin.
What you can do is replace parts of it where you need it to be deformable (if you dont need the whole map to be destructable). It can also be used for tanks,cars, metal objects etc that needs to be deformed during runtime.
If that sounds like a path you could go i could make a quick example of it in action.
