Crystal Shader Breakdown

An unlit/glowing crystal shader with a colour gradient based on object space Y position, and refraction via Scene Color node

URP
Shader Graph

Intro to Shaders

An introduction to what a Mesh, Shader and Material is in Unity, how to set Shader Properties from C#, a brief look at Forward vs Deferred rendering and some information about Material instances and Batching

HLSL

Depth

A big post explaining everything about Depth : Depth Buffer, Depth Texture / Scene Depth node, SV_Depth, Reconstructing World Position from Depth, etc.

Fire Shader Breakdown

A shader which distorts the UVs with noise for sampling a fire texture or shape generated using ellipse nodes

URP
Shader Graph

Sprite Glow/Outline Shader Breakdown

A shader which uses a signed distance field stored in the sprite texture's alpha channel to create an outline/glow (and inner-glow) effect, with control over the colour and thickness

URP

Sprite Stencil Overlay Breakdown

An example of using the RenderObjects feature on the Forward Renderer to produce an overlay effect for sprites (not compatible with the 2D renderer)

Shader Graph

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

Toon Glass Shader Breakdown

A shader which produces solid diagonal lines across a quad's surface that moves with the camera position to simulate toon-like glass reflections

URP
Shader Graph

Fog Plane Shader Breakdown

Two examples of vertical fog effects produced using the depth texture (scene depth)

Cloud Shader Breakdown

A shader applied to a flat subdivided plane where vertices are offset vertically based on layered noise, moving at different rates, to create a cloud effect. Also uses scene depth to produce a softer transition with intersecting game objects
