Unity Shader Graph Skill
Visual shader development using Unity Shader Graph.
Overview
This skill provides capabilities for creating shaders visually using Unity's Shader Graph, enabling artists and developers to build complex materials without writing code.
Capabilities
Visual Authoring
- Create shader graphs for URP/HDRP
- Connect nodes for material logic
- Preview effects in real-time
- Handle shader variants
Effect Types
- Surface shaders (Lit, Unlit)
- Vertex displacement
- UV manipulation
- Procedural textures
Custom Development
- Create custom nodes
- Build subgraphs
- Implement shader keywords
- Handle multi-pass rendering
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
- Use subgraphs for reusable patterns
- Minimize texture samples
- Use shader keywords for variants
- Profile on target platforms
- Document exposed properties
