Creating Custom Shaders

This skill guides creation of GLSL shaders that integrate with the engine's shadow system.

Architecture Overview

The engine uses a shader injection system:

1. You write fragment shaders with custom effects
2. Engine automatically injects shadow uniforms and getShadow() function
3. Use standard vertex shader or write custom one
4. Register shader → Create material → Assign to entities

File Locations

Place shaders in your game's assets folder:
