The Modifier Stac k
Modifier List
The modifier list is a drop-down list that lets you
choose a modifier to add to the stack. When you
choose an object-space modifier (page 1 –557) from
this list, it appears above the object, or ab ove the
modifier that was cur rently selected in the stack.
When you choose a world-space modifier (page
1–512) f rom this list, it appears at the top of the
stack.
Use Pivot Points—The first item in the modifier
list is the Use Pivot Points toggle. It is unavailable
unless multiple objects are selected.
When Use Pivot Points is turned on, 3ds Max uses
the pivot point of each object as the center of a
modifier’s operation. For example, if you bend a
line of trees around the Z axis, they all bend along
their trunks.
When Use Pivot Points is turned off, 3ds Max
calculates a central pivot point for the entire
selection set and modifies the selection as a whole.

Note: You must turn on Use Pivot Points before
you apply the modifier to multiple objects. You
can’t change the setting afterward, although you
can delete the modifier and start over w ithout
deselect in g the selection set.

you can display up to 32 buttons. The buttons are
a shortcut way to add modifie rs to the stack.
