To configure shadows in Three.js, you need to enable shadow maps on the renderer and configure shadow properties on lights. This skill provides practical tips for optimizing shadow bias and shadow maps to maintain performance while achieving realistic renders.

The best way to set up environment lighting is by implementing Image-Based Lighting (IBL). This skill guides you through using environment textures and PMREM-based reflections to achieve realistic lighting and material reflections in real-time web applications.

Use a hemisphere light to simulate gradient lighting from sky to ground, while ambient light applies uniform global illumination. This skill covers the specific use cases for ambient, hemisphere, and other light types to establish the desired scene mood.

Yes, Three.js supports rect area lights which are highly effective for product visualization. This skill provides guidance on adding and tuning rect area lights alongside point, spot, and directional lights for credible real-time rendering.

To optimize Three.js lighting performance on web GPUs, you must carefully manage shadow map resolutions and bias. This skill provides performance considerations and practical tips for real-time rendering to maintain credible lighting without bottlenecking the web-based 3D pipeline.
