This is a sample implementation for SSAO as a RendererFeature in URP. The shader is highly based on this blog post. This has been created for educational purposes, not for production.

Developed and tested on:

• Unity 2019.3.2f1
• Universal RP 7.1.8
• OSX 10.14

This is how it looks:

Debug mode

SSAO active

SSAO inactive

• create or open a URP project
• open "Package Manager"
• click on the "+" icon on the top right
• "Add package from git URL"
• paste "https://github.com/sebastianhein/urp-ssao.git" into the input field
• add new SSAO RendererFeature to the URP settings
• "depth texture" must be enabled in the URP settings

• HDR doesn't work, the SSAO effect uses RGBA32 rendertexture. Needs a check if the current camera target is HDR enabled.
