Procedural materials for coherent NodeMaterial PBR systems in Three.js WebGPU/TSL. Use when a task needs shared identities across PBR channels, must select UV, array, atlas, or projected mapping, needs footprint-filtered normals and specular AA, or needs dynamic per-instance material state with explicit output ownership.
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
# Procedural Materials Build a cause graph, not a collection of channel effects: ```text stable coordinates -> structural causes -> identity weights -> causal modifiers -> filtered microstructure -> NodeMaterial PBR slots -> final-image owner ``` Use `MeshStandardNodeMaterial` for standard opaque/emissive PBR and `MeshPhysicalNodeMaterial` only when its extra lobes or transport properties are part of the surface. Keep Three.js lighting, environment, shadows, and energy handling by assigning node slots instead of replacing the whole fragment output. For multi-system scenes, `$threejs-choose-skills` is an optional coordinator. Fields own shared scalar/vector causes, geometry owns silhouettes, water owns surface/transport, and the final-image pipeline owns tone mapping and display conversion. Consume each dynamic or cross-system cause with declared units, coordinate/frame convention, producer and consumer owners, revision, spatial/temporal support and filter, validity domain, error bound, update cadence, and staleness rule. A visual material state does not become another simulation owner. Initialize and gate the renderer before allocating storage, dispatching …

How to install
mdr add linegel/threejs-complete-set-of-skill/threejs-procedural-materials@sha256:7cff0e42569b5f3bThe line at the top of this page pins the label git:20260924.3a572bb, 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.
