Whetherornottheoperandsarevisible,youcan
transform and animate them at the Oper ands
sub-object level, as with any other object in
3ds Max.
You can also transform and animate the base
object; that is, the first object in the hierarchy view
list.

operand to transfer to the B oolean object in turn.
Before picking each operand, you can change
the Reference/Copy/Move/Instance choice, the
Operation options, and the Apply Material choice.
Tip: When you’re adding many operands to
a Boolean object using the default settings,
calculating the result each time you pick an object

feedback, set Parameters rollout > Display to
Operands. Then, w hen you’re finished, set it back
to Result. Alternatively, on the Advanced Options
rollout set Update to Manually, and then click the
Update button to view the results after performing
the Boolean operations.
Choose a radio button to sp ecify how t he next
operand you pick is transferred to the Bo olean
object:
Reference—The Boolean operation uses a
reference (page 3–1002) to the picked operand,
so the object remains after being incorporated
into the Boolean object. Future modifications
to the originally picked object will also modify
theBooleanoperation. UseReferenceto
synchronize modifier-induced changes to the
original operand with the new operand, but not
vice-versa.
Co pyThe Boolean operation uses a copy of
the picked operand. The selec ted object is
unaffected by the Boolean operation, but a copy
of it participates in the Boolean opera tion.
MoveThe picked operand becomes part of the
Boolean operation and is no longer available
as a separate object in the scene. This is the
default choice.
Instance—The Boolean operation makes an
instance (page 3–957) of the selec ted object.
Future modifications of the selected object will
also modify the instanced object participatin g
in the Boolean operation and vice-versa.
