3d SKILL.md skillA

3d from darknecrocities/skillbuilder is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add darknecrocities/skillbuilder/3d@git:20261025.b510df4

Pins git:20261025.b510df4 in mdr.lock. Pin the fingerprint instead.

Interactive 3D WebGL, Three.js, and React Three Fiber (R3F) engineering skill. Enforces 60fps budgets, PBR materials, Draco compression, and studio lighting.

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

# Interactive 3D WebGL & Three.js Engineering (`/3d`)

> **Philosophy**: *Real-time 3D must be physically grounded and buttery-smooth. Enforce 60fps budgets, Draco compression, PBR physical materials, and strict memory disposal.*

This skill establishes production engineering standards for interactive 3D web applications, real-time product visualizers (e.g., automotive/roadster showcases), Three.js, and React Three Fiber (R3F).

### Rule 1: Physically Based Rendering (PBR) Materials
For premium product visualizations (automotive car bodies, metallic chassis, high-end consumer hardware), use `MeshPhysicalMaterial` rather than basic Phong or Lambert materials:
- **`clearcoat`**: `1.0` (simulates automotive polyurethane clearcoat layer).

How to install

The exact contents, by fingerprint
mdr add darknecrocities/skillbuilder/3d@sha256:0d7fe4cbb77efdf0

The line at the top of this page pins the label git:20261025.b510df4, 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.
