Symmetry
Enables or disables symmetrical vertex map/vertex color editing.
Create a radius within which symmetry should be used. If certain colored points opposite of those you are editing do not react do changes made simply increase the radius accordingly.
Select the coordinate system that should be used for the symmetry plane defined in the Mirror setting. The following three options are available:
The coordinate system will us the currently selected joints/objects.
The world coordinate system will be used.
Selecting this option will let you drag any object into the Object field to be used as a reference for the symmetry layer’s coordinate information.
Select which plane of the coordinate system defined in the Coordinates menu should be used for symmetry. The following options are available:
Any object can be placed into this field to be used as a reference for the symmetry layer. This field will only be made available if Custom is selected in the Coordinates menu.
