■ Collapsing the stack into a surface object such as an editable mesh ■ Controlling whether modifiers are on or off, off in viewports, or off in renderings Collapsing the Stack Collapsing the stack removes modifiers from the object. Collapsing a stack typically converts an object into an editable version of the original object (unless the object was editable to begin with, such as a NURBS model). Collapse To is unavailable unless you select one or more modifiers in the stack. Using Collapse To removes all stack items from the creation parameters to and including the uppermost selected stack item. NOTE You can preserve custom attributes on page 7653 when collapsing the stack. Following are suitable reasons to collapse a stack: ■ To simplify the scene geometry. ■ To discard applied modifiers, and convert the object to an editable object while retaining the results of any applied modifiers. ■ To conserve memory. After you collapse an object's stack, you can no longer parametrically adjust either its creation parameters or its individual modifiers. Animation tracks that were assigned to such parameters also disappear. Procedures To move one or more modifiers: 1 Select one or more modifiers in the modifier stack display. To select multiple modifiers, click to select one modifier, then hold down Ctrl and click to select the others. Holding down Shift selects the two modifiers you click and all modifiers in between them. 2 Right-click and choose Cut. 3 Select a modifier above which to paste the cut modifiers. (This can also be the object at the bottom of the stack.) 4 Right-click and choose Paste. The modifiers are pasted above the current selection. Modify Panel | 7649
