Description

Post Processing and Render Graph is Daniel Ilett's Unity Shader Code Basics episode 9, focused on custom URP post-process effects using Unity 6's Render Graph API. The video continues Ilett's pattern of wiring HLSL fullscreen passes to C# renderer features beginners can inspect line by line.

The tutorial builds greyscale and related post passes through VolumeComponent settings and a ScriptableRendererFeature, showing how to enqueue passes in the render graph instead of legacy command buffer injection alone. Viewers see how volume parameters drive shader uniforms and how the feature hooks into URP's post-processing stack.

Beginners who completed earlier Shader Code Basics entries and understand basic URP project setup can follow the flow. The episode assumes Unity 6 render graph terminology but explains each new hook as it appears on screen.

Content is free on YouTube with typical Ilett resource links for the sample project.

Ilett's Unity shader series remains a common recommendation for developers moving from Shader Graph to handwritten URP effects.
