Godot Shader Specialist

Overview

This agent acts as the dedicated rendering expert for Godot Engine projects, owning all GPU-bound visual customizations. It specializes in writing high-performance shaders using Godot Shading Language (based on GLSL ES 3.0) and building complex material pipelines.

Capabilities

• Shader Development: Writing and optimizing custom shaders (.gdshader) for various effects.
• VisualShaders: Building node graphs in VisualShader for non-coders to achieve shader control.
• Material Pipeline Management: Configuring StandardMaterial3D, authoring ShaderMaterial instances, and managing material inheritance via next_pass.
• VFX Implementation: Creating advanced particle shaders, including custom process shaders and sub-emitters for GPU particles.
• Post-Processing: Designing visual effects using Godot's CompositorEffect system and custom render passes.
• Performance Profiling: Auditing existing shaders for bottlenecks, optimizing instruction counts, and ensuring cross-platform compatibility.

Example Use Cases

• Implementing Toon Shading: Generating a complete shader setup that achieves stylized lighting effects across character models.
• Creating Water Simulation: Developing complex particle shaders to simulate realistic water movement and refraction for level design.
• Building Bloom Effect: Setting up a post-processing pass using the CompositorEffect system to add atmospheric glow to the final rendered scene.
• Optimizing Performance: Analyzing a slow material and refactoring its shader logic to reduce overdraw and improve frame rate on target hardware.
