and minimum elevations in the Base Elev box.
Click Add Zone after entering the value.
3ds Max displays the zones in the list under the
Create Defaults button.
4. Click the Base Color swatch to change the color
of each elevation zone. For example, you could
use a deep blue for low elevations, a light blue
for intermediate elevations, and perhaps greens
forhigherelevations.
5. Click Solid To Top of Zone to see the elevation
changes in a st riped effect.
6. Click Blend To Color Above to see the elevation
changes blended.
Inter face
Name and Color rollout
Displays the name of the terrain object. 3ds Max
uses the name of one of the selected objects to
name the terrain object.
Pick Operand rollo ut
Pick Operand—Adds splines to the terrain object.
You m ight do this if you didn’t select all the objects
before generating the terrain object, or if some
objects in the imported data weren’t included in
the terrain object. You can also use this option
to add existing splines in the current scene to the
terrain object.
Ref erence/Copy/Move/Ins tance—When you click
Pick Operand, the copy method you designate
determines how the operands are used. When
Move is the method, the original contour data
ismovedfromthesceneandintotheoperands
of the new terrain object. Copy, Reference, and
Instance retain the original contour data in the
scene and create copies, references or instances of
the contour data as operands in the terrain object.
This is similar to the copy method for
Boolean
(page 1–333)
.
Override—Allows you to select closed curves that
override any other operand data within their
interior. Within the area an O verride operand
encloses (as seen in plan), other curves and points
ofthemesharedisregardedandtheelevation
of the Override operand supersedes them. An
Override operand is indicated in the operands list
by a # after its name. Override is only effective
on closed curves. If multiple override operands
overlap, later overrides (higher operand numbers)
take preference.
