Post effect

Post Process

Use Post Process to help improve the visual quality of the camera view and apply specific camera effects to create stylized visual effects.

Add Post Process component to Camera

Go to the Hierarchy panel to select the Camera object. 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 the Camera component.

Add Post Process effects

Navigate to the Post Process component and click Add Effect. Select the effect you would like to apply to the camera view.

Bloom

  • Fast mode: When checked, the performance is improved 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. Integers reduce the calculation time and improve the quality.
  • Intensity: The strength of Bloom.
  • Soft Knee: Creates gradual transitions between under/over-threshold. 0 is a hard threshold while 1 is a soft threshold.
  • Clamp: Clamps the pixels to control the maximum Bloom.
  • Anamorphic ratio: This distorts the Bloom to simulate an anamorphic lens. The number represents the direction of distortion. Negative values distort vertically while positive values distort horizontally.

FXAA

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

Chromatic Aberration

  • Spectral Lut: You can change this to a custom color bar texture.
  • Fast mode: When checked, it improves performance by sacrificing quality. It’s generally recommended for mobile and low-end platforms.
  • Intensity: The strength of aberration. Values range between -10 and 10. The more extreme the value, the more intense the effect is. The default value is 0.7.

Distort

  • BarrelPower: The strength of the 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 the amplitude of dynamic distortion in x and y directions.
Tip
Tip

You need to set up non-zero x or y value for Amplitude in order to see the results of Speed and Frequency values.

  • Frequency: Controls the frequency of dynamic distortion in x and y directions.
  • Speed: Control the speed of dynamic distortion in x and y directions.
  • Offset: Fordynamic distortion, control the offset to the distortion center (screen center)in x and y directions.

Grain

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