Mirror Direction Options Naming Weights ToolDirection
Defines the position of the mirror plane in the viewport. The following options are available:
Places the mirror plane at the position of the selected object.
Places the mirror plane at the position of the top joint in the hierarchy.
Places the mirror plane at the position of the selected object's parent object.
Places the mirror plane at the position of the first parent object in the hierarchy whose Hub option is enabled on the Symmetry tab.
Places the mirror plane at the position of the object selected in the Object link field.
Places the mirror plane at the world origin.
Places the mirror plane at the position of the first object whose Weight tag contains weights for the joint objects that are to be mirrored.
Short for Coordinates. Defines which coordinates system will be used to orient the mirror plane, based on its Origin mode.
Uses the World axis coordinates system to orient the mirror plane.
Uses the local object axis coordinates system to orient the mirror plane, as defined by the selected Origin mode (for example, if Parent is selected as Origin mode, the plane will be oriented based on the coordinates of that parent object).
Will use the current view coordinates system to orient the mirror plane. This will change interactively as you change your view (for example, mirroring from the front view will not have the same result as mirroring from the side view).
If World or Local coordinates are selected to orient the mirror plane, this option will become active, enabling you to set the mirror plane axis manually.
Will mirror along the X axis (YZ plane).
Will mirror along the Y axis (XZ plane).
Will mirror along the Z axis (XY plane).
Allows you to define the direction toward which elements will be mirrored.
Will automatically decide which side the elements should be mirrored to. An element located on the positive side of the mirror plane will be automatically mirrored to its negative side, and vice-versa. Make sure that your mirror plane is set properly, otherwise the object will not mirror at all (if it's placed on the origin of the mirror plane, for example).
Will mirror elements from the positive axis side to the negative axis side (from +X to -X, for example).
Will mirror elements from the negative axis side to the positive axis side (from -X to +X, for example).
