In-Depth Information
1. Let's you extend the edges of the terrain. It basically does the same as
altering NumPatches in the properies window.
2. The standard paint tool raises or lowers the terrain and paints or un-paints
texture and foliage layers.
3. Flatens the area based on the height of the vertex where the operaion
started. Everything is raised or lowered to the height of the vertex where
you started dragging.
4. Smoothens the area. Also works for blurring texture layers.
5. Flatens an area using its average height.
6. Adds noise to either the geometry or texturing of the terrain.
All of these are controlled by the Strength: , Radius: , and Falloff: sliders. Pre-sets are
available in the Brush secion, although, I personally ind those rather useless.
Any of these tools can be used by holding Ctrl on your keyboard and dragging the
mouse over the terrain while holding the let or right mouse buton. A right-click
usually does the opposite of a left-click. For example, left-clicking will raise the
terrain and right-clicking will lower the terrain again.
7.
If the Strength , Radius , or Falloff sliders are not powerful enough for you, it is also
possible to manually type in a value in the text field next to the sliders, to further
bump up their power. This is especially handy for huge terrains that require large
brushes to get around:
