Unity Shader Graph

Material System

• Generate materials from graphs
• Expose material properties
• Handle texture sampling
• Implement triplanar mapping

Prerequisites

• Unity 2021.3+
• Shader Graph package
• URP or HDRP project

Usage Patterns

Common Node Patterns

Dissolve Effect:
Noise → Step → Alpha Clip Threshold → Alpha

Rim Lighting:
Fresnel Effect → Multiply → Add Emission

Scrolling UV:
Time → Multiply → Add UV → Sample Texture

Vertex Animation:
Noise → Position Offset → Position

Custom Function Node

// Custom HLSL function for Shader Graph
void MyCustomFunction_float(float3 In, out float3 Out)
{
    Out = In * 2.0;
}

Best Practices

1. Use subgraphs for reusable patterns
2. Minimize texture samples
3. Use shader keywords for variants
4. Profile on target platforms
5. Document exposed properties
