In the UDK documentation there is the description of a method for using landscape Alphamaps/Weightmaps that are a higher resolution than the heightmap to which they correspond. In this way, more precise detail can be painted on the landscape without having to scale the heightmap up accordingly. These are referred to as “Super Masks”.
My question: is there an equivalent method in the Unreal Engine 4, that would allow for landscape alphamaps/weightmaps that are higher resolution than the heightmaps they correspond to?
E.g. if I had a heightmap resolution of 256 (257) but wanted to use a weightmap of 512 or 1024.
