SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill solves the complexity of configuring real-time lighting, shadow maps, and environment-based illumination in Three.js, preventing common issues like shadow acne, performance bottlenecks, and flat-looking renders.

Core Features & Use Cases

  • Lighting Rigging: Provides templates for 3-point studio setups and various light types including Ambient, Directional, Point, Spot, and RectArea lights.
  • Shadow Optimization: Offers configuration patterns for PCSS/PCFSoft shadow maps, bias tuning, and frustum management to balance visual quality with performance.
  • Environment Integration: Simplifies the loading of HDR environments and PMREM generation for high-fidelity PBR materials.

Quick Start

Use the threejs-lighting skill to configure a directional light with soft shadows and an HDR environment map for a standard scene.

Frequently Asked Questions about threejs-lighting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I fix shadow acne and optimize shadow maps in Three.js?▼

To fix shadow acne in Three.js, tune shadow bias and configure PCSS or PCFSoft shadow maps. This approach prevents shadow artifacts while balancing visual quality against rendering performance through careful frustum management.

How do I use HDR environment maps for PBR lighting in Three.js?▼

Use HDR environment maps for PBR lighting in Three.js by loading HDR files and generating PMREM textures. This workflow provides accurate environment-based illumination and high-fidelity reflections for physically based materials.

What is the best way to set up a three-point studio lighting rig in Three.js?▼

Setting up a three-point studio lighting rig in Three.js involves configuring Ambient, Directional, Spot, and RectArea lights. These templates simulate studio-grade illumination for web-based 3D rendering and high-quality visual setups.

Can I manage light budgets for real-time Three.js web rendering?▼

You can manage light budgets for real-time Three.js web rendering by applying light configuration patterns. This process restricts active light counts and optimizes shadow frustums to maintain performance without sacrificing visual fidelity.

Why does my Three.js scene render flat despite using multiple lights?▼

Three.js scenes render flat when lacking proper environment-based illumination and PBR material integration. Loading HDR environments and generating PMREM textures adds realistic reflections and global illumination to prevent flat-looking renders.
