S_UltraGlowGenerates varieties of glowing light from bright areas of the source clip. Raise the threshold parameter to produce glows in fewer areas. Adjust the Width RGB parameters to make glows with different color falloffs, and adjust the Width XY parameters to make horizontal or vertical glows. Adjust Glow Falloff and Glow Bias parameters to control falloff distance and how far the hottest areas extend. Adjust After Glow parameters to generate a secondary glow on the result of the primary glow. Optionally enhance the edges or add highlights to the source clip or combine the result with atmospheric noise.In the Sapphire Lighting category.
