Use the Flip To Right Flip To Left flip options to replace one side of the groom with a mirrored version from the opposite side. For example, if you select Flip To Right, all of the splines from the right side of the mesh are removed and replaced with a mirrored version of the left side splines. After using these options, you may need to use a brush to touch-up areas close the center line of the surface.
Applies automatic smoothing for splines that have been oriented or posed. The smoothing effect averages out any splines that might have been missed by a brush stroke. Auto Twist only effects splines that have been bushed with a sculpting operation such as Bend.
Removes the current groom and resets the attributes to default settings.
Deletes any masks that have been painted on surface.
