rust SKILL.md skillA

rust from wolffe/three.js-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add wolffe/three.js-skills/rust@git:20261031.845cf45

Pins git:20261031.845cf45 in mdr.lock. Pin the fingerprint instead.

Create realistic procedural rust, oxidation and corrosion with Three.js TSL on WebGPU. Use for rails, exposed steel, machinery, pipes, bridges, containers, ships and old infrastructure.

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

# Rust and Corrosion

Target: Three.js 0.187.0, `three/webgpu` and TSL node materials from `three/tsl`; WebGPU only, no WebGL fallback, no GLSL strings.

Rust is a physical surface transformation, not merely an orange colour.

## Layer model

Think:

clean coating
-> scratched coating
-> exposed metal
-> oxidation
-> rust
-> heavier corrosion
-> pitting

The amount of each layer should be controlled by masks.

## Corrosion masks

Use plausible causes:

- exposed edges
- seams
- water traps
- damaged paint
- bolt interfaces
- joints
- lower sections
- drainage paths
- sheltered crevices

Avoid uniform procedural rust noise.

## Properties affected

Rust should influence several properties:

- base colour
- roughness
- normal
- specular response
- metallic response where appropriate

Heavily corroded regions should not retain the same smooth reflective appearance as pristine metal.

## Geometry vs shader

Use shader detail for small corrosion and surface variation.

Use actual geometry for major holes, deep flaking, broken edges and large missing material when it affects silhouette or close-up shape.

## Match corrosion to environment and maintenance

How to install

The exact contents, by fingerprint
mdr add wolffe/three.js-skills/rust@sha256:fa229416be03c14e

The 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.
