material-composition SKILL.md skillA
material-composition from wolffe/three.js-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add wolffe/three.js-skills/material-composition@git:20261031.845cf45Pins git:20261031.845cf45 in mdr.lock. Pin the fingerprint instead.

Combine realistic TSL materials into coherent multi-material objects in Three.js WebGPU scenes. Use when an object (vehicle, building, machine) is made of several physically distinct surfaces.
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
# Material Composition
Target: Three.js 0.187.0, `three/webgpu` and TSL node materials from `three/tsl`; WebGPU only, no WebGL fallback, no GLSL strings.
Complex objects should be composed from physically distinct surfaces rather than forced into one universal shader.
## Typical object composition
A train might contain:
- painted aluminium/steel body
- glass windows
- rubber seals
- polished or brushed metal components
- dark underbody metal
- plastic interior components
- lights/emissive elements
A building might contain:
- concrete
- painted steel
- aluminium
- glass
- rubber seals
- weathered surfaces
- interior materials
## Separation rule
If two parts have different physical construction, give them separate material treatment where useful.
Do not create dozens of materials for negligible differences.
## Shared material vocabulary
Prefer reusable material constructors and parameter sets.
For example:
createPaintMaterial({ color, roughness, wear })
createGlassMaterial({ tint, roughness, thickness })
createMetalMaterial({ type, roughness, wear })
createRustMaterial({ severity, moisture })

How to install
mdr add wolffe/three.js-skills/material-composition@sha256:42094dbcd742249eThe line at the top of this page pins the label git:20261031.845cf45, 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.
