Pulse color: Make the pulse animation affect the color of the image.Pulse alpha: Make the pulse animation affect the opacity of the image.Blend mode: How the pulse color is blended with the background image.By default the entire image will pulse, so in most cases you want to paint the opacity mask to limit the effect of the pulse to certain areas of the image (mainly areas you want to light up). Opacity mask: A paintable mask to determine which area of the image is affected.The following settings are shared across both modes: The effect has two different modes, a standard one and an audio response mode. It can either pulsate a light in set intervals or react to any audio being played on the system. The Pulse effect can is useful for animating any type of lighting.
