Shading Lights name starts with: Only Lights that begin with this name will considered by the effect. All the other lights in the composition are ignored.
Ambience: The amount of color to be inherited by all the points, irrespective of their location and proximity from a point light. For example if the value is 10%, all the points receive 10% of the color from every shading light in the composition irrespective of their distance from the light.
Effect Only Group: Only vertices in this group will be affected by this effector. If “All Groups” is selected all points in the Plexus are affected.
