Can I use this skill to set up HDR environment maps?

Absolutely. It includes patterns for using RGBELoader and PMREMGenerator to implement Image-Based Lighting (IBL) for realistic material reflections.

Which Three.js light types are supported by this skill?

The skill covers AmbientLight, HemisphereLight, DirectionalLight, PointLight, SpotLight, and RectAreaLight, providing specific code snippets for each.

How do I fix shadow acne or detached shadows?

The skill provides guidance on using shadow bias and normalBias settings to resolve common artifacts like shadow acne and 'peter-panning'.

Does this skill help with shadow performance optimization?

Yes, it provides best practices for shadow map sizing, tightening shadow camera frustums, and using light layers to reduce rendering overhead.
