SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill removes the trial-and-error of setting up believable lighting in Three.js scenes by giving you a clear playbook for illumination, shadows, and environment lighting.

Core Features & Use Cases

  • Choose the right light type for each scene, including ambient, hemisphere, directional, point, spot, and rectangular area lights.
  • Configure shadow casting, shadow softness, bias, map size, and camera bounds to improve visual quality without wasting performance.
  • Build common production lighting setups such as three-point studio lighting, outdoor sunlight, indoor product scenes, and animated light motion.
  • Use environment maps, light probes, helpers, and light layering to support physically based materials and more controllable rendering results.

Quick Start

Use this skill to create a Three.js lighting setup for your scene by combining a key directional light, soft ambient fill, shadow settings, and an environment map that fits your performance budget.

FAQPage Schema
How do I configure realistic Three.js lighting for an outdoor daylight scene?

To configure realistic Three.js lighting for outdoor daylight, you combine a key directional light with a soft ambient or hemisphere fill. This skill provides the exact setup to balance illumination and performance for daylight environments.

What's the best way to tune shadow softness and bias in Three.js?

Tuning shadow softness and bias in Three.js involves adjusting shadow map size, bias, and camera bounds. This skill configures these shadow parameters to improve visual quality and eliminate artifacts without wasting rendering performance.

How do I set up three-point studio lighting in Three.js?

Setting up three-point studio lighting in Three.js requires layering directional, area, and ambient lights. This skill provides production-ready templates for studio setups, ensuring controllable illumination for product visualization and animated scenes.

Does Three.js environment mapping work with physically based materials?

Yes, Three.js environment mapping works with physically based materials by using environment maps and light probes. This skill configures environment lighting to support reflections and provide accurate ambient fill for PBR rendering.

Why do my Three.js shadows look pixelated or have jagged edges?

Pixelated or jagged Three.js shadows usually result from low shadow map sizes or tight camera bounds. This skill helps you tune shadow map resolution and light camera bounds to render clean, high-quality shadows.

Can I use rectangular area lights for indoor product visualization in Three.js?

Yes, you can use rectangular area lights for indoor product visualization in Three.js. This skill guides you through selecting and positioning area lights alongside environment lighting to achieve realistic studio illumination.
