Use for hybrid texture-backed PBR soil and moss with procedural displacement and masks, upward-facing model moss accumulation, atlas filtering, specular AA, planet-space fields, terrain wetness, lava and emissive surfaces, reflective wave-optical diffraction gratings, air-film-air soap bubbles with Airy interference, raytraced diamond and gem refraction with internal reflection and dispersion, image-space glass transmission with spectral dispersion and volume absorption, per-instance dissolve, authored PBR identities, derivative normals, and custom direct-light shadow modulation.\n---\n\n# Procedural Materials\n\nBuild a material from surface identity and causes. Color, roughness, metalness, normal, transmission, and emission should describe the same surface—not unrelated noise textures.\n\nThis skill contains exemplary examples and assets beyond descriptive guidance,\nthey're worth studying, referencing, or even copying. Use them sufficiently\nwhen relevant and do NOT blindly skip them.\n\n## Material graph order\n\n```text\nstable coordinates\n  → structural fields\n  → material identity weights\n  → causal modifiers\n  → filtered microstructure\n  → PBR channels\n  → lighting/shadow extensions\n```\n\nRead [references/procedural-pbr-system.md](references/procedural-pbr-system.md)\nfor atlas filtering, specular AA, planetary coordinates,\nworld-height wetness, per-instance dissolve, and authored PBR response bundles.\n\nRead the\n[sculpted gallery frame geometry](../threejs-procedural-geometry/examples/sculpted-gallery-frame/frame-geometry.js)\nfor walnut, antique-gold, and ebony texture/roughness/metalness/clearcoat\nbundles under a grazing-light setup.\n\nRead the\n[procedural planet surface](../threejs-procedural-planets/examples/procedural-planet-surface/planet-system.js)\nfor shared geological, climate, water, biome, roughness, and derivative-normal\ncauses on a procedural planetary surface.\n\nRead the\n[analytic wave optics](../threejs-water-optics/examples/analytic-wave-optics/water-system.js)\nfor coupled reflection, refraction, absorption, filtered microstructure,\nresolved crest response, and their diagnostic channels.\n\nRead the\n[lava flow surface material](examples/lava-flow-surface/lava-surface.js)\nfor raymarched procedural height fields whose normals, rock/lava identity,\nemission, glow, embers, fog, and grain are coupled to one material cause stack.\n\nRead the\n[raytraced diamond material](examples/raytraced-diamond/diamond-material.js)\nfor a gem whose mesh is its own optical volume: camera-ray entry refraction, a\nGPU BVH first-hit loop with bounded total-internal-reflection bounces,\nper-channel IOR dispersion, mip-correct environment exit sampling, and live\ncamera-matrix uniforms.\n\nRead the\n[spectral dispersive glass material](examples/spectral-dispersive-glass/spectral-glass-material.js)\nfor a transmissive body solved in image space: a double-sided back-face data\npass with inverted depth, an iterative interior exit search, bounded total\ninternal reflection, Beer-Lambert absorption over the true path length, and a\nper-wavelength Cauchy index recombined through CIE 1931. Its reusable optical\nprimitives — exact unpolarised Fresnel, Cauchy coefficients, spectral weights,\nthe rotatable environment probe, and the buffer projection — live in\n[glass optics](examples/spectral-dispersive-glass/glass-optics.js), and\n[references/dielectric-glass-optics.md](references/dielectric-glass-optics.md)\ncarries the two-pass contract, buffer format, search bounds, and transmission\ndiagnostics.\n\nPick between the two transmissive paths by geometry, not by quality. A closed\nfaceted gem whose exit facet must be exact even when it faces away from the\ncamera takes the BVH path. A scanned, assembled, open-sheet, or multi-shell\nbody takes the image-space path, which tolerates inconsistent winding and\nauthored normals pointing either way but cannot see a surface outside the\nframe.\n\nRead\n[references/physical-diffraction-grating.md](references/physical-diffraction-grating.md)\nfor the exact embossed-field, CIE/blackbody spectral, phase-grating, Bessel\norder-efficiency, coherence-broadening, strip-emitter, additive-layer, stable\nobject-frame, limitation, and diagnostic contracts.\n\nRead the\n[physical diffraction-grating implementation](examples/physical-diffraction-grating/physical-diffraction-grating.js)\nfor a printed substrate plus additive HDR foil response whose star and stripe\nmasks select local groove angle, pitch, and relief while wavelength alone owns\nspectral colour. Its complete optical model is expressed as a pure TSL graph\nwith `Fn`, `If`, and `Loop`, without embedded native shader source.\n\nRead\n[references/thin-film-soap-bubble-system.md](references/thin-film-soap-bubble-system.md)\nfor the air-film-air Airy equation, representative RGB spectral bands,\ntwo-membrane blending, bounded secondary reflection, capillary mechanics,\ncamera-aware inflow, puncture retraction, limits, and diagnostics.\n\nRead the\n[thin-film soap bubble system](examples/thin-film-soap-bubbles/soap-bubble-system.js)\nwhen soap-film interference must drive the image: it provides wavelength-\ndependent aqueous index, front and rear membrane passes, analytic nearby-\nbubble reflection, volume-preserving capillary modes, buoyancy and drag,\nTaylor-Culick rupture, visible-drop aftermath, and deterministic physics gates.\n\n## Required controls\n\n- real or perceptual texture scale;\n- material identity weights;\n- roughness range and micro-normal strength;\n- the causal fields required by the selected material pattern;\n- for a transmissive body, the physical constants that define it — index and\nAbbe pair, interior path budget, extinction depth — named rather than buried\ninside expressions;\n- for a soap film, the exterior and film indices, nanometre thickness range,\n  wavelength bands, surface tension, and membrane ordering;\n- distance/derivative filtering;\n- specular antialiasing;\n- channel and mask debug modes.\n- emissive-material debug modes when the material owns glow or volumetric\naccumulation.\n\nRead [references/hybrid-soil-moss-surface.md](references/hybrid-soil-moss-surface.md)\nand the\n[hybrid soil and moss implementation](examples/hybrid-soil-moss-surface/hybrid-soil-moss-surface.js)\nfor texture-backed soil and moss albedo, AO, roughness, and normal microdetail\ncombined with procedural mound displacement, moisture, moss coverage/height,\nand warped cellular cracks. Do not describe its surface identity as fully\nprocedurally synthesized. When moss must also settle onto a model, read the\n[model moss implementation](examples/hybrid-soil-moss-surface/model-moss-accumulation.js)\nfor model-locked coverage, upward-face accumulation, displaced thickness, and\nshared moss PBR identity.\n\n## Failure conditions\n\n- every PBR channel samples independent noise;\n- roughness is a scalar afterthought;\n- high-frequency normals survive below one pixel;\n- triplanar projection has visible orientation or scale seams;\n- atlas padding is ignored under mipmapping;\n- custom lighting removes energy conservation without an explicit stylized goal;\n- post-processing is used to hide unstable highlights.\n- diffraction hue is painted from UV instead of derived from wavelength;\n- a groove frame follows the camera or world axes instead of the object;\n- a narrowed diffraction lobe loses energy because its density lacks sigma normalization.\n- a soap bubble is treated as a solid glass sphere or painted with a rainbow instead of using air-film-air interference;\n- a deformed soap membrane retains the undeformed sphere normal;\n\n## Routing boundary\n\nUse `$threejs-procedural-fields` when the main problem is designing shared\nscalar/vector causes. Use `$threejs-procedural-planets` for a complete\norbit-to-close-approach body, not merely its material. Use\n`$threejs-parallax-occlusion-mapping` when a height field must own ray-marched\nintersection, silhouette coverage, or relief-aware shadows. Use\n`$threejs-temporal-surfaces` for view-aligned wet-glass optics and screen-space\nhistory; this skill owns the optical path through a transmissive body itself.\n","tagline":"Author production procedural materials in Three.js.
