SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill helps you design and tune Three.js lighting so 3D scenes look natural, readable, and performant without trial-and-error guesswork.

Core Features & Use Cases

  • Light Selection: Choose the right light type for daylight, studio setups, flashlights, bulbs, or soft area illumination.
  • Shadow Configuration: Enable, debug, and optimize shadows with practical settings for quality, softness, and performance.
  • Environment Lighting: Add image-based lighting and reflections with HDR or cube textures for physically based materials.
  • Use Case: A developer building a product viewer can combine directional light, soft shadows, and HDR environment lighting to make models look realistic across devices.

Quick Start

Use the threejs-lighting skill to recommend a complete lighting setup for my Three.js scene, including suitable lights, shadow settings, and environment lighting.

Frequently Asked Questions about threejs-lighting

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

FAQPage Schema
How do I set up realistic Three.js lighting and shadows for a 3D scene?▼

Three.js environment lighting uses HDR or cube textures to apply image-based lighting, generating accurate reflections and ambient light for physically based materials without manual light placement.

What's the best way to optimize Three.js shadow quality and performance?▼

Optimizing Three.js shadow performance involves tuning shadow map resolution, softness settings, and light coverage boundaries to balance visual fidelity against rendering overhead across target devices.

Does Three.js environment lighting work with physically based rendering materials?▼

Yes, Three.js environment lighting integrates with physically based rendering by using HDR environment maps to provide image-based illumination and accurate surface reflections on PBR materials.

Why do my Three.js shadows look pixelated or not rendering correctly?▼

Pixelated Three.js shadows typically result from low shadow map resolution, incorrect light camera frustum settings, or disabled shadow casting on meshes, all of which require targeted shadow configuration adjustments.

Can I use Three.js helpers to debug lighting and shadow setups?▼

Yes, you can add Three.js helpers to visualize light positions, directions, and shadow camera frustums, making it easier to debug and align lighting configurations within your 3D scene.
