Light and shade a three.js scene: choose materials (MeshStandardMaterial PBR vs unlit MeshBasicMaterial), add ambient/hemisphere/directional/point/spot lights, turn on shadow maps, and use an environment map (IBL) for realistic reflections. Use when a three.js model looks black, flat, or wrong — when the user mentions three.js materials, MeshStandardMaterial, lights, shadows, envMap, or PBR. For renderer/loop setup use threejs-scene-setup; for loading models use threejs-gltf-loading.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# three.js Materials & Lighting Make three.js surfaces look right: pick the correct material, light the scene, enable shadows, and add image-based lighting. Patterns target **r186**, verified against **r186** (lighting is physically based by default since r155). ## When to use - Use when a mesh renders black or flat, when choosing a material, adding lights, enabling shadows, or setting up environment-map reflections (IBL). - Use when code constructs `MeshStandardMaterial`, `DirectionalLight`, etc., or sets `renderer.shadowMap.enabled` or `scene.environment`. **When *not* to use:** the renderer/camera/loop → `threejs-scene-setup`. Loading models (whose PBR materials this complements) → `threejs-gltf-loading`. Custom GLSL/`ShaderMaterial` is its own topic; for the portable concept see `shader-programming`. ## Core workflow 1. **Pick a material by need.** `MeshStandardMaterial` (PBR: `roughness`, `metalness`, reacts to lights/IBL) for realism; `MeshPhysicalMaterial` for clearcoat/transmission; `MeshBasicMaterial` (unlit, ignores lights) for UI/flat; `MeshNormalMaterial`/`MeshDepthMaterial` for debugging. …

How to install
mdr add gamedev-skills/awesome-gamedev-agent-skills/threejs-materials-lighting@sha256:5377a67ebd805857The line at the top of this page pins the label git:20260925.a8320b7, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
