- A gentle introduction to shaders (Alan Zucconi)
Alan Zucconi's A gentle introduction to shaders in Unity3D (June 2015) is part one of his Gentle Introduction series on alanzucconi.com, aimed at Unity developers new to GPU programs.
It connects vertices, materials, and shaders in Unity's pipeline, covering ShaderLab Properties and SubShader layout, inspector uniforms, Queue tags, ZTest, and the surface-versus-vertex/fragment split for lighting versus effects.
Little prior shader knowledge is assumed; fixed-function shaders are skipped as obsolete.

Believable Caustics Reflections is Alan Zucconi's September 2019 Unity blog post on faking pool-style ripple caustics without ray tracing, sparked by Florian Gelzenleuchter's popular shader GIF.
One tileable texture is sampled twice in a Surface shader at different scales and scroll speeds, combined with min(), then tinted onto albedo with slight RGB UV offsets for dispersion.
The walkthrough covers _ST tiling, _Time animation, HDR albedo above 1.0, and Post Processing Stack v2 bloom.

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.

Constraint-Based Tile Generators is BorisTheBrave's October 2021 survey unifying WaveFunctionCollapse and Model Synthesis as constraint-based tile generators that fill a grid under hard local rules.
Boris organizes variants by model (adjacency versus overlapping patches), constraint inference from samples, labels, or tile borders, solvers from arc consistency to Z3, cell and tile heuristics, contradiction handling, and non-square grids.
