Comb Settings

Property	Description
Mode	Set how the brush affects strands or curves. For details about the different modes, refer to Groom modes.
Pull	Set how the comb affects the strands.
	Both	Comb strands in both directions.
	Front	Only comb strands in front of the brush.
	Back	Only comb strands behind the brush.
Reactivity	Set the reactivity of the brush. Lower values make the brush more stable, meaning it's slower to swivel to face a new direction as you move it around.
Root/Tip Weight	Skew the effect of the brush toward the roots or toward the tips of the strands or curves. Lower values push the effect towards the root, and higher values push the effect towards the tip.
Preserve Length	Maintain the length of the hairs when combing (the brush can't stretch or shrink hairs).
Backface Culling	Groom only strands growing from surfaces that are facing the camera. This property lets you groom hair on one side of a surface without affecting the back. If this property is disabled, all strands covered by the brush are groomed.
