DelayBasic Coord. Effector Parameter Deformer
The Delay Effector ensures that the effects of other Effectors with regard to position, scale and rotation do not begin abruptly, but with a specified temporal delay. Basically an effect trail is dragged behind the corresponding Effector.
The Delay Effector should be arranged after the Effectors it should affect, i.e., it should be arranged after (below) these Effectors in the MoGraph object’s Effector list in the Effector tab.
Spring is a very useful option for letting clone movements look more realistic. Using the Delay Effector saves time because adjustments to the Timeline (e.g., Curves) are done more-or-less automatically that result in realistic movements.
