A waterfall shader that interacts with a sphere to part the flowing water. Uses a signed distance field and alpha clipping.
Custom Renderer Features
Goes through examples of Renderer Features and explains how to write Custom Renderer Features and Scriptable Render Passes for Universal RP. Mostly focuses on Unity 2022, but now also provides some snippets for newer versions!

An example of using the RenderObjects feature on the Forward Renderer to produce an overlay effect for sprites
Dissolve Shader Breakdown
A shader which uses noise and step functions to discard pixels to create a dissolving effect. Also provides examples for dissolving based on height / Y and using view space position as UVs to avoid seams
