How it works...
The function of most of the buttons is pretty self-explanatory, but let's look at what happens
when either of them are applied.
A little bit of smoothing is something that might be needed after generating a heightmap
using an automated tool. In such a case, you most likely won't use a brush, though, but
rather a filter that will apply it evenly across the whole of the heightmap. The brush might
instead be used to smooth out an area where a game character is supposed to move to make
it a better game experience. It might also be that the ground of an area is of a type that
would most likely be smoother than the surroundings, like a beach among rocky cliffs.
Level terrain has similar uses. If we need sufficient space to place a large building for ex-
ample, it is the best way to ensure that no part of the building ends up floating or sub-
merged beneath the ground.
