SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Metal shader development on Apple GPUs is complex and performance-critical. This skill consolidates decades of production-grade knowledge into accessible guidance, helping engineers and artists write efficient, correct Metal Shaders and debug performance issues quickly.

Core Features & Use Cases

  • Expert guidance on Metal Shading Language (MSL) across vertex, fragment, compute, and tile shaders
  • Production-ready patterns for PBR lighting (Cook-Torrance BRDF), energy conservation, and TBDR optimization
  • Debugging, profiling, and performance tuning workflows, references, and practical examples for iOS/macOS apps
  • Clear integration patterns with existing graphics pipelines, shaders, and tooling for Apple GPUs

Quick Start

Create a simple Metal project in Xcode and implement a basic PBR shader using the Cook-Torrance BRDF reference to observe real-time results.
