- Blur Renderer Feature Example/Template for URP / Unity 2021.2 (Alexander Ameye)
Custom Render Passes in Unity is Alexander Ameye's July 2021 ameye.dev note on URP ScriptableRendererFeature and ScriptableRenderPass boilerplate, heavily commented where Unity SRP documentation still feels sparse.
The sample applies a two-pass box blur: blit camera color to a temporary buffer, blur vertically then horizontally, with adjustable strength and downsampling.

Ronja’s tutorial 046 demystifies HLSL partial derivatives: ddx and ddy measure how a value changes across 2×2 pixel quads, and fwidth combines them for screen-space-aware filtering.
Demonstrates greyscale debug views, then builds an anti-aliased step (aaStep) that widens cutoffs by one pixel’s gradient - reducing jaggy fire, toon bands, and procedural edges versus raw step().
Includes a scrolling noise fire shader comparing step, aaStep, and smoothstep.
