Mirror Function

Select one of the following options:

Behavior

When this option is on, the mirrored joints have the opposite orientation as the original, and the local rotation axis of each joint points in the opposite direction of their counterparts.

This setting is handy for animating opposing movements in a pair of counterpart limbs. For example, if you select a pair of ankles and use the Rotate tool on both at the same time, you can rotate the feet to point symmetrically inward or outward with a single manipulation.

Orientation

When this option is on, the mirrored joints have the same orientation as the original joints.

With this setting, you can copy animation from one limb to another and get identical behavior. For example, if you want to animate a skier racing down a slope with legs turning in the same direction, use this setting.

Replacement names for duplicated joints

Select one of the following options:

Search For

Lets you specify the name identifier of the joints in the mirrored joint chain that you want to replace.

For example, if you type “right_” in this field, all of the mirrored joints with the “right_” prefix in their name will change to what is specified in the Replace With field.

Replace With

Lets you specify the names with which to replace the mirrored joint name identifiers specified in the Search For field.

For example, if you type “left_” in this field, all the “right_” prefixes of the mirrored joint names will be replaced with “left_”.
