Post effect

Post Process

Post process helps to improve the visual quality of the frame and apply specific camera effects to create stylised visual effects.

Quick start

Add Post Process component

Go to the Hierarchy panel to select the Camera object, then go to the Inspector panel and click + Add component > Post Effect > Post Process to add the component.

Tip
Tip

Post Process can only be assigned to the entity with Camera component.

Add Bloom effect

Navigate the Post Process component, and click Add Effect > Bloom. This will activate Bloom effect along with related parameters for setting.

Post process properties

Bloom

Fast mode: When checking this option, it will improve the performance by sacrificing the quality of Bloom. It’s generally recommended for mobile and low-end platforms.

Threshold: Filters out brightness under this level to bloom

Color: The color of bloom

Diffuse: This changes the extent of veiling effects. Prefer to use integers for higher quality to reduce calculation.

Intensity: The strength of bloom

Softknee: Makes gradual transition between under/over-threshold gradual (0 = hard threshold, 1 = soft threshold).

Clamp: Clamps the pixels to control the maximum bloom

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

Chromatic Aberration

Fast mode: When checking this option, it will improve the performance by sacrificing the quality. It’s generally recommended for mobile and low-end platforms.

Intensity: The strength of aberration. Values range between -10 and 10. The higher the absolute value, the more intense the effect is. The default value is 0.7.

Distort

BarrelPower: The strength of distortion. The positive and negative values represent different styles of distortion. Values range between -1 and 1.

Rotation: The rotation of the screen. Values range between -360 and 360.

Zoom: The rotation of the screen. Values range between -1 and 1.

Amplitude: Controls dynamic distortion and represents the amplitude of distortion in x and y direction.

Frequency: Controls dynamic distortion and represents the frequency of distortion in x and y direction.

Speed: Controls dynamic distortion and represents the speed of distortion in x and y direction.

Offset: Controls dynamic distortion and represents the offset of distortion in x and y direction.

Grain

Strength: The strength of grain. Values range between 0 and 1.

Color: The color strength of grain. Values range between 0 and 1.

Speed: The blinking strength of grain. Values range between 0 and 10.

Vignette

Power: The range of the dark vignette area.

Contrast: The softness of the vignette. The lower the value, the smoother the vignette border. Values range between 1 and 50.

FXAA

Fast Approximate Anti-Aliasing will give graphics a smoother appearance.
