The Modifier Stack
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 1–537)
from this list, it appears above the object, or above
the modifier that was currently selected in the
stack. When you choose a
world-space modifier
(page 1–498)
from this list, it appears at the top
of the stack.
Use P ivot 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 turn ed on, 3ds Max u ses
thepivotpointofeachobjectasthecenterofa
modifier’s operation. For example, if you b e nd 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.
For example, if you bend a line of trees around the
Z axis, trees at the end of the line deform more

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 without
deselect in g the selection set.
Modifier Buttons
Between the modifier list and the stack display,
you can display up to 32 buttons. The buttons are
a shortcut way to add modifiers to the stack.
