Bloom

Bloom creates an illusion of a bleeding light around the light source, providing a glow-like effect.

In the Demo Effect section, you will learn how to apply Bloom to a cube to create glow effect. Download the following file to get started:

Bloom Properties

Fast Mode: Improves the performance by sacrificing the quality of Bloom. This option is recommended for mobile and low-end platforms.

Threshold: Filter out the brightness under this level to Bloom.

Color: The color of Bloom.

Diffuse: Change the extent of veiling effects. Integers are recommended for higher quality to reduce calculation.

Intensity: The strength of Bloom. 

Soft Knee: Make a gradual transition between under or over-threshold. 0 is a hard threshold while 1 is a soft threshold. 

Clamp: Clamp the pixels to control the maximum Bloom.

Anamorphic Ratio: Distort the Bloom to simulate an anamorphic lens effect. The number represents the direction of distortion. Negative values distort vertically while positive values distort horizontally.
