4 Tutorials - Volcano - Page 2: Modifying the Landscape
Take
a moment to think about some of the conditions around our volcano.
When mud and lava erupt and flow down the slopes, the flows carve
deep troughs into the landscape.
These
carved areas basically break up the surface, which is one visual
characteristic of very large objects (like volcanoes).
Let' s
apply an Erosion Filter to the Landscape mesh. This
will carve out some interesting-looking furrows into the slopes
and simulate some of the effects of mudflows at the base of
the mountain.
Right-click
on the Skin property, drag down to Add…
Select
Landscape Erosion Type II and click OK. Use the
default settings in the Property Page.

Let' s
check our adjustments in a new render.
Our
volcano will need some material shading. In the Library' s
materials group, select the sand02 material and drag
it onto Area 1 (full).
|
| Render
the scene again.
That' s
quite an improvement, but we still need to work on the impression
that this is a mountainous object. Trees scattered around
the base of the volcano will also help to enhance its sense
of scale.

|
| Make
a new Area on Landscape0, around the base of
the volcano, and (mostly) within camera range. In the
Library, select GrandFir 1 from the trees group.
|
|
| 
|
Select
Area2 in the Scene tree and drag GrandFir 1 onto
it in the Properties Tree.
|
| Choose
Scattered Vegetation in the Select Type(s) of Object
dialog box. |
