Setting up a three-point lighting rig in Three.js involves configuring standard light types like Ambient, Directional, Point, Spot, and RectArea lights to achieve professional studio illumination and eliminate flat visuals.

Shadow acne in Three.js occurs due to incorrect shadow map depth precision; you can mitigate it by applying bias correction and optimizing shadow map rendering pipeline settings.

Using HDR environment maps for Image-Based Lighting in Three.js provides high-fidelity environment mapping and realistic outdoor daylight simulation by capturing physically accurate light falloff.

Yes, you can optimize Three.js lighting performance by integrating light probes, which provide performance-optimized environment lighting calculations for complex 3D environments.

The best way to achieve physically accurate light falloff in Three.js is by configuring advanced lighting systems that support realistic outdoor daylight and studio environment mapping.
