Create stunning and realistic light ray effects quickly and easily. Known as volumetric lighting in computer graphics or crepuscular rays in atmospheric optics, this dramatic effect adds polish and style. Since the rays are only added to highlight areas, they have the effect of passing through objects and add a third dimensional quality. Add shafts of light streaming through clouds, rays filtering through a forest canopy, beams of light on a foggy night or rays shooting out from text. Rays adds a striking and dramatic quality to any image.

Light.

Determines the blend mode to be used to create the rays effect.

Move the point control in the center of the screen to change the source point from which the rays will emanate.

Sets the ray length.

Sets the brightness of the rays.

Sets the color of the rays.

Blurs the rays.

Controls the amount of rays based on a brightness threshold. Fewer rays with more definition are generated at higher threshold values.

A circular light source can be used to enhance the generation of the light rays. It is particularly useful when the image does not have strong highlights.

Sets the brightness of the light source.

Sets the size of the light source.

Adds texture to the rays.

Sets the amount of texture.

Sets the size of the texture.

Sets the randomness of the texture.

Randomizes the rays.

Sets the amount of shimmering.

Sets the randomness of the shimmering.

Sets the opacity of the rays.

Sets the opacity of your image.

The rays modify the alpha channel.

The rays are generated from the alpha channel instead of the RGB channels. In this case, the rays will not use color from the image and will typically be brighter. Values between 0 and 100 interpolate between using the RGB and the alpha.

Composites the image over the rays.
