SSGI-URP

Screen Space Global Illumination for Universal Render Pipeline. It's a port of a SSGI shader wrote by Martins Upitis for the Godot Engine. It's adapted to work as a render feature for Unity's Universal Render Pipeline.

Keep in mind it's a simple implementation of SSGI and it's not perfect. Performances are good if you keep noise and sample count low.

Requirement

  • Unity 2019.3+
  • Universal Render Pipeline 7.2+
  • Depth Texture Enabled
  • Tested on Windows 10

Debug SSGI Enabled

Enabled SSGI Disabled

Setup

Parameter Role
SamplesCount How many samples to use. A value between 8 and 16 is fine for performances
IndirectAmount Indirect GI Boost. No cost on performances
NoiseAmount Add some noise to the final render, impact performances, keep it lower to 2
Noise Enable or not the noise

Usage

  • Create or open a URP project
