Visit resource ↗Description
(cyanilux.com) is Cyan's personal site for free Unity shader tutorials, organized into long-form Posts and effect-focused Breakdowns with expandable screenshots.
Posts explain Shader Graph basics, depth, vertex displacement, custom URP renderer features, and render passes. Breakdowns cover water, forcefields, holograms, dissolves, outlines, foliage, rain, and GPU-instanced grass.
The material suits intermediate technical artists and graphics programmers using URP and Shader Graph; most examples target Unity 2019 - 2022 APIs, with notes on HDRP and newer editor differences.
Tutorials are free online, with GitHub tools such as ShaderGraphVariables and custom-lighting subgraphs. Shader code, graphs, and C# snippets are CC0 unless a page specifies otherwise.
The site is widely recommended in Unity shader discussions, and ShaderGraphVariables is often cited for Shader Graph gaps.
