A custom fullscreen post-processing effect for Unity 6 (Universal Render Pipeline) that recreates the low-resolution, color-crushed look of PlayStation 1 era graphics.
Built as a proper URP Volume override, so you can control it per-scene, blend between volumes, and animate parameters at runtime — just like any built-in post-processing effect.
- Resolution downscaling — Render at a fraction of the screen resolution (default 0.35x) and upscale with point filtering for that chunky pixel look
- Color depth reduction — Reduce bits per channel to simulate PSX color banding (set to 5-8 for authentic results)
- Volume integration — Works as a standard URP Volume override, supports blending and per-camera control
- Non-destructive — Runs before post-processing, so bloom, color grading, and other effects still apply on top
- Unity 6 (6000.0+)

- Copy the
Assets/Scripts/Rendering/folder into your project - Select your URP Renderer Asset (e.g.
PC_Renderer) - Click Add Renderer Feature → PSX Pixelization Feature
- The shader auto-resolves. If it doesn't, drag
PSXPixelization.shaderinto the shader slot
- Select your Global Volume (or create one: GameObject → Volume → Global Volume)
- In the Volume Profile, click Add Override → Post-processing → PSX Pixelization
- Enable the override and check Enabled
- Adjust parameters:
| Parameter | Range | Default | Description |
|---|---|---|---|
| Enabled | on/off | off | Toggle the effect |
| Render Scale | 0.05 – 1.0 | 0.35 | Resolution multiplier. Lower = more pixelated |
| Color Depth | 2 – 32 | 32 | Bits per channel. Lower = more color banding |
