target object, showing how the projection will
be done. Default=off.
Push group
These controls let you adjust the size of the cage
as a whole, or on a sub-object selection if one is
currently chosen (see Reference Geometry Rollout
(Projection Modifier) (page 1–772)).
Amount—Changetoadjustthesizeofthecage
in 3ds Max units. Positive values increase the
size of the c age; negative values decrease the size.
Default=0.0.
Percent—Changetoadjustthesizeofthecage
as a percent age. Positive values increase the size
of the cage; negative values decrease the size.
Default=0.0.
Auto-Wrap group
By default, the Projection modifier does not
automatically create a cage that wraps around the
geometry. To change the cage, use the settings
in this group or the Push group, or adjust cage
vertices manually at the C age sub-object level.
Tolerance—Thedistancein3dsMaxunits,
between the cage and the target geometry. Positive
values are outside the hig h-res source geometry ;
negative values are inside the source geometry.
Default=varies, depending on the geometry.
Alway s Update—When on, the cage automatically
expandsaroundhigh-resgeometryasitisaddedto
the list (see Reference Geometry Rollout (Projection
Modifier) (page 1–772)). When off, the initial cage
is not updated automatically. Default=off.
Update—Click to update t he cage. Use this when
Always Update is off.
Impor t—Lets you specify a mesh object to
define the cage s hape. This is typically an object
that was created with Export (see following)
and then modified using standard mesh-editing
methods. After clicking Import, select the object
to import. After importing the object, the cage
conforms to its shape. You can then delete the
imported object if you wish.
Impor tant: Theimportedobjectshouldbeofthesame
type (for example, editable mesh) as the projection
object(thatis,theobjectwiththeProjectionmodifier),
or be convertible to that type without topology change,
and must have the identical topology. If it doesn’t
meet either or both of those criteria, an alert appears
requesting that you select a n object of the same type
and identical topology.
Export—Creates a geometry object from
thecage,withthesametypeandtopologyas
the mo dified object. Clicki ng Export causes t he
Expor t C age dialog to open. Accept the default
“Export as” object name or enter a new one, and
then click OK.
For a detailed description of the expor t /import
process, see To use E x p ort and Import with a cage:
(page 1–773).
Reset—Click to reset the cage to a wrapping
that is the same size as the low-resolution t arget
geometry.

This rollout lets you check select ions to see if any
are overlapping; that is, if a material ID or a face or
element is a ssigned to more than one select ion.
