I simply need this engine feature for my little strategy game (I utilized terrain deformation in the engine I’m switching from to ue4, where it is very simple, to make moats and to smooth terrain at building placement positions by simple terrain vertex heigh manipulation with vertex normal and collision shape update).
fortunately, I can wait for this while I’m working on more important game parts, and probably I would spend a little money on it if someone could make it in future if Epic does not find it important.
