Modify panel > Modifier stack display > Right-click a modifier or object.
Some commands for managing modifiers are available by right-clicking the modifier stack display. Some options are unavailable if they don't apply to the current modifier. For example, Make Unique is available only if you select an instanced modifier.
The main uses of the right-click menu for the modifier stack are:
Renaming modifiers
Rearranging modifiers using cut, copy, and paste
You can cut, copy, and paste multiple modifiers at one time. You can also cut and copy discontiguous selections of modifiers.
Creating instances of modifiers
Collapsing the stack into a surface object such as an editable mesh
Controlling whether modifiers are on or off
The right-click menu for the modifier stack replaces the Edit Stack dialog.
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). 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.
Following are suitable reasons to collapse a stack:
To simplify the scene geometry.
To discard applied modifiers, and convert the object to an editable mesh 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:
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.
Right-click and choose Cut.
Select a modifier above which to paste the cut modifiers. (This can also be the object at the bottom of the stack.)
Right-click and choose Paste.
The modifiers are pasted above the current selection.
To copy one or more modifiers:
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.
Right-click and choose Copy.
Select an item above which to paste the cut modifiers.
Right-click and choose Paste.
The copied modifiers are pasted above the current selection.
Choose Paste Instanced to make the pasted modifiers instances of those you copied.
Select one or more modifiers in the modifier stack display of the first object.
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.
Right-click and choose Copy.
Select the second object.
In the second object's modifier stack display, select an item above which to paste the copied modifiers.
Right-click and choose Paste.
The modifiers from the first object are pasted above the current selection in the second object.
Choose Paste Instanced to make the pasted modifiers instances of those you copied.
Interface
Rename: Lets you change the name of the modifier. For example, you might change the name Bend to the more specific "First 45-degree bend." After choosing Rename, enter the new name in the stack display, and then press ENTER. Pressing ESC cancels the name change.
Delete: Deletes the modifier from the stack. The modifier is not available for pasting.
Cut: Cuts the modifier from the stack. The modifier is removed, but is available for pasting.
Copy: Makes a copy of the modifier that is available for pasting.
Paste: Pastes the modifier into the stack. The modifier appears above the currently selected object or modifier, unless it is a world space modifier, in which case it is pasted at the top of the stack.
You can paste a modifier from one object into the stack of a different object.
Paste is unavailable when more than one modifier is selected in the stack.
Paste Instanced: Pastes an instance of the modifier into the stack. The modifier instance appears above the currently selected object or modifier, unless it is a world space modifier, in which case it is pasted at the top of the stack.
You can paste a modifier instance from one object into the stack of a different object.
Paste Instanced is unavailable when more than one modifier is selected in the stack.
Make Unique: Converts an instanced modifier to a copy that's unique to the current object. This button is unavailable unless the modifier you right-clicked is instanced. See Make Unique.
Collapse To: Collapses a portion of the stack. Collapse To is unavailable unless you select one or more modifiers in the stack. Using Collapse To collapses all stack items from the object itself, up to and including the uppermost selected stack item. If there are modifiers above the uppermost selection, they are not changed.
The result of a collapse depends on the base object. A geometric primitive, with or without modifiers, collapses into an editable mesh. Editable Polymeshes collapse to editable polymeshes.
World-space modifiers don't collapse along with the rest of the stack.
Collapse All: Collapses the entire stack.
The result of a collapse depends on the base object. A geometric primitive, with or without modifiers, collapses into an editable mesh. Editable Polymeshes collapse to editable polymeshes.
World-space modifiers don't collapse along with the rest of the stack.
On: Turns on the effect of the modifier.
The lightbulb icon to the left of the modifier name shows "on."
Off: Turns off the currently selected modifiers without deleting them. This can help you see the object without the effect of its modifiers.
The lightbulb icon to the left of the modifier name shows "off."
Make Reference: If the object is an instance, converts it to a reference. This option is available only when the base object is selected, and only when the base object is a reference.
When you make an instanced object into a reference, a heavy, "derived object" bar appears at the top of the stack. You can select this bar and apply modifiers above it. Modifiers applied above the bar affect the reference object only, and not its parent object.
Gray bar denotes a reference object at the base of the stack
Show All Subtrees: Expands the display of every hierarchical item in the stack display, so that all items in the stack are visible, including sub-objects.
Hide All Subtrees: Hides the subtree of every hierarchical item in the stack display, so that only objects, modifiers, and space warp bindings are visible.
