Easing curve is not used. \value ScaleAffector3D.AbsSineWave The scale follows the sine wave except negative values are inverted. Easing curve is not used. \value ScaleAffector3D.Step The scale stays at minimum size until half of the duration milliseconds have passed then steps directly to the maximum size. Easing curve is not used. \value ScaleAffector3D.SmoothStep The scale smootly transitions from minimum to maximum size. Easing curve is not used.
