meshy-3d

meshy-3d is a skill for Claude Code, Codex from calesthio/generative-media-skills. It costs 199 tokens per session (7,024 once invoked), scanned A, original, MIT.

A guide to Meshy, a hosted service that generates 3D models from text or images. It also covers texturing, material maps, remeshing, polygon count, UVs, rigging, animation, and exports such as GLB, FBX, OBJ, and USDZ.

In plain words
What is it for?
Use it to create, texture, optimize, rig, animate, and export 3D assets from prompts or reference images.
Why use it?
It helps control the generation process and judge whether the resulting model is suitable for a game, film, or 3D-printing workflow. It also explains how to track the service's asynchronous jobs through completion.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

meshy-3d scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Meshy 3D generation

Meshy is a hosted generative-3D service. You give it text or images; it returns a textured mesh (GLB/FBX/OBJ/USDZ/STL/3MF), with optional PBR maps, remeshing, UV, auto-rigging, and library animations. Everything runs as asynchronous jobs: you POST a task, get a task ID, then poll, stream (SSE), or receive a webhook until SUCCEEDED.

This skill covers driving Meshy well: choosing the right generation mode, writing prompts that separate geometry from texture, controlling topology and poly count, texturing and re-texturing, rigging and animating, exporting into a game/film/print pipeline, and judging whether the output is usable.

Evidence labels used below

  • [Doc] — stated in official Meshy documentation, API reference, or help center (URLs in Sources). Volatile items carry a verification date.
  • [1P-claim] — a first-party Meshy claim (marketing/blog/help) not independently verified. Treat as a claim, not a guarantee.
  • [Heuristic] — production judgment from how generative-3D pipelines behave; verify against your own output.

Volatile facts (model IDs, credit costs, limits, formats) were verified 2026-07-10 against docs.meshy.ai. Re-check the changelog and pricing pages before quoting numbers to a user, because Meshy ships model versions and adjusts credit costs and promotions frequently.

When to use Meshy — and when not to

Use Meshy when you need:

  • A single, coherent prop, character, or creature fast from a prompt or a reference image (concept-to-asset, game jam, previz, background dressing, crowd fillers, marketplace assets, 3D-print blanks). [Heuristic]
  • A textured starting mesh you will clean up downstream rather than a final production hero asset. [Heuristic]
  • Bulk asset generation where throughput and cost per asset matter more than authored topology. [Heuristic]

Do not reach for Meshy when:

  • You need exact real-world dimensions or CAD tolerances (mechanical parts, enclosures, mounting brackets). Generative meshes are approximate; use CAD. [Heuristic]
  • You need guaranteed-watertight, manifold geometry for manufacturing. Meshy offers printability analysis/repair and remesh, but does not guarantee a manifold result; validate in a slicer/mesh-repair tool. [Heuristic]
  • You must edit the geometry of an existing hand-authored asset — Meshy regenerates, it does not surgically edit your mesh.
  • The subject is a full scene (room, environment, multiple interacting objects). Text-to-3D and image-to-3D reconstruct one subject best; build the scene from separately generated parts in your engine. [Doc/Heuristic]
  • You require clean animation-ready quad topology with edge loops around deformation areas authored to spec. Meshy's quad remesh is quad-dominant reconstruction, not artist-placed edge flow. [Heuristic]
  • Licensing forbids AI-generated assets, or your reference images are copyrighted in a way that would taint ownership (see Rights & licensing).

meshy-3d is a skill published in the GitHub repository calesthio/generative-media-skills (170 stars, last pushed 1mo ago), licensed MIT. It adds 199 tokens to every session and 7,024 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
