Threejs Lighting

This covers the full Three.js lighting toolkit from basic ambient and directional lights through spotlights, point lights, and RectAreaLight for soft illumination. You get detailed shadow configuration including map sizes, bias settings, and frustum tuning for each light type, plus environment-based lighting with HDR maps. The shadow optimization section is genuinely helpful, showing you how to fix acne artifacts and balance quality versus performance. If you're setting up realistic lighting or debugging why your shadows look wrong, the concrete examples for each light's shadow camera setup will save you time. The IBL section gets cut off but the fundamentals are solid.
