Polygon Properties rollout
These controls let you work with material IDs and
smoothing groups.
Material group
Set ID—Lets you assign a particular mater ial ID
(page 3–1063)
number to selected sub-objects for
use with
multi/sub-object materials (page 2–1403)
and other applications. Use the spinner or enter
the number from the keyboard. The total number
of available IDs is 65,535.
Select ID—Selects sub-objects corresponding to
the Material ID specified in the adjacent ID field.
Type or use t he spinner to specify an ID, t hen click
the Select ID button.
[Sel ect B y Name]—This drop-down list shows
the names of sub-materials if an object has a
multi/sub-object material assigned to it. Click the
drop arrow and choose a sub-material from the list.
This selects any sub-objects assigned that material.
If an object does not have a multi/sub-object
material assig ned, the name list is u navailable.
Likewise, if multiple selec ted objects have an Edit
Patch, Edit Spline, or Edit Mesh modifier applied,
thenamelistisinactive.
Note: Sub-material names are those specified in the
Name column on the mater ial’s multi/sub-object
Basic Parameters rollout. By default, 3ds Max
assigns the material name “No Name” followed by
a sequence number in parentheses. These names
don’t appear in the Material Editor, but they do
show up in the drop-down list.
Clear Sel ection—When on, choosing a new ID or
material name unselects any previously selected
sub-objects. When off, selections are cumulative,
so new ID or sub-material name selections add to
the existing selection set of patches or elements.
Default=off.
