Great, now we know what each brush does, but we can take the control we have
over the terrain to the next stage by tweaking the brush size and speed. These two
settings can be found next to five brushes and the next screenshot shows the names
of each bar:
It is obviously the
Brush Size
setting that controls the terrain, but we can be
confused by what the brush speed does. The easiest way to explain this setting is by
testing it, so let's start by selecting the Raise brush and set the
Brush Size
setting to
the highest value, which is
5
. To control the value of the brush size, we need to click
on the bar with the left mouse button and drag from left to right in order to increase
the value.
The next step is setting the brush speed to the lowest value,
1
. Now, click once with
the left mouse button on the terrain. Did you see any change on the terrain? Probably
not, so now, we need to change the brush speed to the highest value,
5
, and click
again on the terrain with the left mouse button. Now, we saw a small bump being
raised in the terrain. Do you understand how the brush speed works? The brush
speed controls the relation between the time we press the left mouse button and
the speed or the amount of change that is applied to the terrain. This creates an
opportunity to use different brush sizes to add different layers of details to the terrain.
It requires patience and skill, but the final result can help to sell the scene as realistic.
We may think that it is great to have a small bump in the terrain, but we really
would love to have our terrain the way it was before this testing.
