another object, the box will have only two m aterial
IDs, instead of the six it was assigned on creation.
Match M aterial to Mater ial I Ds—Maintains the
original ID assig nment in the attached objects
by adjusting the number of sub-materials
in the resulting multi/sub-object material.
For example, if you attach two boxes, both
assigned single m aterials, but with their default
assignment of 6 material IDs, the result would b e
a multi/sub-object material with 12 sub-materials
(six containing instances of one box’s material,
and six containing instances of the other box’s
material). Use this option when it’s important to
maintain the original material ID assignments in
your geometry.
Note: If you want to m a ke the instanced
sub-materials unique, select them in Track View,
andclicktheMakeUniquebuttonontheTrack
View toolbar. You can also make them unique
one at a time with the Make Unique button (page
2–1442) in the Material Editor.
Do Not M odify Mat I Ds or Material—Does not adjust
the number of sub-materials in the resulting
sub-object material. Note that, if the number of
materialIDsinanobjectisgreaterthanthenumber
of sub-materials in its multi/sub-object material,
then the resulting face-material assignment might
be different after the attach.
Condense Material IDs—Affect s the Match Material
IDs To Material option. When this is on, duplicate
sub-materials or sub-materials that aren’t used in
the objects are removed f rom the multi/sub-object
material that results from the attach operation.
Default=on.
Tips
• In most cases, use the first option (Match
Material IDs to Material) while keeping
Condense Material IDs selected. This
maintains t he appearance of the objects, and
results in the fewest additional sub-materials
or IDs.
•Usethesecondoption(MatchMaterialto
Material IDs) when you need to maintain the
original material ID assignments.
• Avoid using the third option, unless you need
to repeat a 3ds Max version 1 attachment for
compatibility with a previous project.
• Leave Condense Material IDs selected unless
you have an unassigned sub-material that you
want to keep for future assignment.
• Perform Edit menu > Hold before performing
the attach.

let you subdivide edges and faces to create new
vertices, edges, and faces. You can slice an editable
mesh object at any sub-object level; the Cut tool
is available at every sub-object level except the
Vertex sub-object level.
Procedures
To crea te a new f a ce usin g Cut:
1.
Convert the geometry to an editable mesh.
2. On the Modify panel, choose the
object’s Edge (or Face, Polygon, or Element)
sub-object level.
3. On the Select ion rollout, turn on Ignore
Backfacing.
4. On the Edit Geometry rollout, in the Cut and
Slicegroup,clicktheCutbutton.
5. Click the first edge you want to subdivide, and
then move your cursor toward the second edge.
