Parametric Deformers

Mirror

The Mirror modifier provides a parametric method of mirroring an object or a sub-object selection. You can apply the Mirror modifier to any type of geometry, and you can animate the mirror effect by animating the modifier's gizmo.

Mirroring a bench

TipWhen modeling the left or right side of a character for mirroring to the opposite side, use the Symmetry modifier to create the other side. Its Weld Seam feature helps create a more natural-looking model.

Procedures

To apply the Mirror modifier:

Apply the Mirror modifier to a selection.
Set the axis or axis pair on which to mirror the object.
To create a mirrored pair, specify an Offset amount and turn on Copy.

Interface

Modifier Stack

Mirror Center: Represents the axis of the mirror effect. You can move, rotate or scale the gizmo to affect the mirroring. You can animate the gizmo transforms, which you can't do with the toolbar Mirror tool.

For more information on the stack display, see Modifier Stack.

Parameters rollout

X, Y, Z, XY, YZ, ZX: Specify the axis or axes about which the mirroring takes place. You can usually see the effect in the viewport as you select the option.
