Three.js PBR materials use MeshStandardMaterial or MeshPhysicalMaterial with color, roughness, metalness, normal, and occlusion texture maps to achieve physically based rendering. This setup ensures realistic light interaction across meshes in 3D scenes.

MeshStandardMaterial supports PBR workflows with metalness and roughness properties, while basic, phong, and toon materials offer stylized or non-physical shading. Choosing between them balances visual realism against rendering performance needs.

Apply texture maps to a Three.js mesh by assigning image textures to material properties like map, normalMap, and roughnessMap. This drives surface detail and PBR realism without adding geometric complexity to the underlying mesh.

Use custom shader materials when built-in PBR, phong, or toon materials cannot achieve specific visual effects or performance targets. Shader materials allow direct GLSL control for advanced rendering workflows and optimized visual patterns.

Yes, the material configurations support environment maps to enable realistic reflections and refractions. Applying environment maps to MeshStandardMaterial and MeshPhysicalMaterial enhances PBR accuracy by providing ambient lighting data.

Optimize Three.js material performance by reusing established material patterns across multiple meshes instead of creating unique instances. Selecting basic or phong materials over complex PBR shaders also reduces rendering overhead in dense scenes.
