Extrude Modifier 681
Inter face
Amount—Sets the depth of the extrusion.
Segments—Specif ies the number of segments that
wi ll be created in t he extr uded object.
Capping group
Cap Sta rt—Generates a flat surface over the start
of the ext ruded object.
Cap End—Generates a flat surface over the end of
the extruded object.
Morph—Arranges cap faces in a predictable,
repeatable p attern, w hich is necessary for creating
Morph targets (page 1–314).Morphcapping
can generate long, thin faces that don’t render
or deform as well as grid capping. Use morph
capping primarily if you’re extruding multiple
morph targets.
Grid—Arranges cap faces in a s quare gr id trimmed
at the shape boundaries. This method produces a
surface of evenly sized faces that can be deformed
easily by other modifiers. When you choo se the
Grid capping option, the grid lines are hidden
edges rather than visible edges. This primarily
affects any objects assigned a material with the
W ire option turned on, or an y objects that use the
Lattice modifier (page 1–709).
Output group
Pat ch—Produces an object that you can collapse to
apatchobject;seeEditing the Stack (page 1–504).
Mesh—Produces an object that you c an collapse to
a mesh object; see Editing the Stack (page 1–504).
NUR B S —Produces an object that you can collapse
to a NURBS surface; see Editing the Stack (page
1–504).
Genera te M apping Coords—Applies mapping
coordinates to the extruded object. Default=off.
When on, Generate Mapping Co ordinates applies
separate mapping coordinates to the end caps,

Real-World Map Size—Controls the scaling method
used for texture mapped materials that are applied
totheobject. Thescalingvaluesarecontrolled
by the Use Real-World Scale settings found in
the applied material’s Coordinates rollout (page
2–1625).Default=on.
Generate Ma terial IDs—Assigns different material
IDstothesidesandthecapsoftheextruded
object. Specifically , the sides receive ID 3, and the
caps receive IDs 1 and 2.
This check box is turned on as a default when
you create an extruded object, but if you load an
extruded object from a MAX file, the check box
is turned off, m aintaining the same material ID
assignmentforthatobjectasithadinR1.x.
Use S ha p e ID s—Uses the material ID values
assigned to segments in the spline (page 1–266)
you extruded, or curve sub-objects in the NUR BS
(page 1–1078) curve you extruded.
