Post-Processing Effects

Post-Processing Effects

Post-Processing applies full-screen filters and effects to the camera's rendered image before it is drawn on the screen (similar to photo filters).

URP Post-Processing Setup

To enable post-processing in URP:

1. Select your Main Camera in the Hierarchy.
2. In the Camera component settings, check the Post Processing box.
3. Create a Volume GameObject (GameObject -> Volume -> Global Volume).
4. Create a Volume Profile asset in the Volume component.

Common Effects (Overrides)

Click Add Override in the Volume component to add effects:

• Bloom: Causes bright areas in the image to bleed light edges, creating a glow effect (e.g., glowing lava or lights).
• Color Adjustments / Color Grading: Modifies white balance, contrast, saturation, and color filters.
• Vignette: Darkens the corners of the screen to focus attention on the center.
• Depth of Field: Blurs background or foreground elements, simulating real camera lens focus.
• Motion Blur: Blurs the screen in the direction of fast camera movement.

TL;DR

• Post-processing applies filters to the final camera output.
• Cameras must have Post Processing enabled in their properties.
• Global Volumes apply effects to the entire scene.
• Add Overrides like Bloom, Vignette, and Depth of Field to customize the style.
