Raising and Lowering Terrain
To raise or lower terrain, perform the following tasks:
- Select Activate terrain editing
(
) to enable terrain editing within the Design
View.
- Within the Terrain Editor window, click Raise/Lower.
- Optionally, specify a custom brush radius, a brush softness, and
a height:
- Brush radius: In the Brush
Radius field, specify a number between 1 and 2147483647
(231 - 1). The default
value is 3.
A small number defines a small radius for the brush cursor with
which you raise or lower terrain, and a larger number defines
a larger radius. A small radius allows you to design fine detail,
whereas a large radius allows you design large areas quickly.
- Brush softness: In the Brush
Softness field, specify a number between 0 and 1. The default
value is 0.5.
A small number defines a harder brush, which produces harsher lines
for the raised or lowered terrain, whereas a larger number defines
a softer brush, which produces more rounded contours for the raised
or lowered terrain.
- Height: In the Height
field, specify a number between 0 and 3.4028E+038 (3.4 x 1038). The default value is
0.5.
The height defines how much terrain is raised or lowered with each
click (or click and drag). A smaller number raises or lowers the
terrain by a small amount, whereas a larger number raises or lowers
the terrain by a large amount.
- To raise terrain: Within the Design View, position the cursor where
you want to raise terrain and left-click. You can also left-click
and drag to raise areas of terrain.
- To lower terrain: Within the Design View, position the cursor where
you want to lower terrain and Control-left-click. You can also Control-left-click
and drag to lower areas of terrain.
The following figure shows some raised and lowered terrain (a chasm
and some mountains) using the default settings.
