Use for large procedural worlds, city scenes, terrain, moving cameras, WebGPU/TSL shadow nodes, cascades, cached clipmaps, texel stabilization, update budgets, and targeted invalidation.\n---\n\n# Shadow Systems\n\nUse a single shadow map only when its receiver region is genuinely bounded. For large moving views, make shadow coverage an explicit spatial hierarchy.\n\n## Cached clipmap workflow\n\n1. Define concentric light-space square levels.\n2. Snap each level center to its own texel grid.\n3. Cross-fade adjacent levels in shader space.\n4. Refresh near levels continuously.\n5. Cache coarse levels and update them under a frame budget.\n6. Invalidate intersecting levels when important casters or streamed terrain change.\n7. Scale normal bias by world-space texel width.\n\nRead [references/cached-clipmap-shadows.md](references/cached-clipmap-shadows.md) before implementing a large-world directional light.\n\nRead the\n[cached shadow clipmaps](../threejs-procedural-architecture/examples/procedural-financial-tower/shadow-clipmaps.js)\nfor three light-space square levels, per-level texel snapping, containment\ncross-fades, cached coarse updates, scaled bias, and unshadowed outside weight.\n\n## Failure conditions\n\n- projection centers move by fractions of a texel;\n- shader containment does not match the map's committed center;\n- all cascades refresh every frame without evidence;\n- coarse levels freeze moving casters indefinitely;\n- depth texture samples occur in divergent fragment control flow;\n- the same normal bias is used across radically different texel sizes;\n- level boundaries become visible under camera motion.\n\n## Routing boundary\n\nUse this skill for light-space directional shadow maps. Use\n`$threejs-screen-space-ambient-occlusion` for view-dependent ambient\nvisibility; AO is not a replacement for cast shadows.\n","tagline":"Implement stable, scalable directional-shadow systems for Three.js.
