Pulls vertices along with the movement of the brush to create long, snake-like forms. During the stroke, geometry will be dynamically picked up & let go.
When the Rake setting is used, the brush can also be used to rotate geometry via dragging.
Pulled geometry tends to lose volume along the stroke. With Magnify value greater than 0.5 this is prevented. More info at Pinch/Magnify
Rotates geometry along the direction of the stroke.
