Meshy 3D Generation
Use Meshy CLI 0.7 (0.7.3 or later) to turn the user's request into a delivered asset. Completion means saving the requested files in the requested location, inspecting an available preview, and finishing any project integration the user requested. Login or task submission alone is not completion. Choose the shortest suitable pipeline and reuse existing assets for follow-ups.
Read what this request needs
| Need | Reference |
|---|---|
| CLI runner, credentials, or output location | Setup |
| Generation, texturing, remeshing, conversion, scale, or 2D images | Pipelines |
| Rigging, animation, or generated motion | Animation |
| Cost, waiting, preview, delivery, or finding a previous model | Delivery |
| Failed or uncertain operation | Troubleshooting |
Read the relevant section when needed; recipes are examples to adapt to the requested result, not a requirement to execute every stage. An untextured model skips texture generation; an existing GLB needs no extra format conversion. Use command help when parameters are uncertain.
First use and authorization
Before the first command run meshy --version; no need to ask. When meshy is missing or
older than 0.7.3, install the newest 0.7.x with npm install -g meshy-cli@0.7 and say so in
one line; Setup covers a refused install and a CLI of 0.8 or newer. Reuse a verified session. If login is
needed, follow Setup and run auth login --device (adding --region cn for a user in mainland
China) in a persistent tool session. Show its
verification URL and user code in commentary/progress, not a final answer. Await that same
session in this turn until it exits, verify auth status, then continue the original request.
A background process cannot resume a finished turn; do not require a "done" chat message, except in
Setup's two-step sign-in for a user on a remote chat (a phone through a chat bot).
Browser approval stays with the user; credentials never belong in chat.
Execution boundaries
- Run API, upload, download and mesh operations through the CLI. Local inputs have a 50 MiB limit, and a local model must be GLB or glTF (rigging, UV unwrap and multicolor: GLB); use the supported URL input route for anything else.
- Use
--format json --no-update-checkon every command: stdout is onemeshy.cli/v1envelope, auth included. ResolveWORKSPACEfrom the user's output path and pass it to writes. - Submit once with
create --async, retain the owning resource and ID, thenwaiton that task. Keep the agent turn active while awaiting a running command. Follow Troubleshooting on timeout or unknown submission; these do not authorize another paid create. - Continue work within the user's approved scope and budget. Propose additional paid stages or reruns before spending; Delivery specifies estimates and balance checks.
Deliver
Download only needed assets. Inspect and show a preview when available; a missing preview must not prevent delivery or be described as inspected. Delivery covers earlier-stage preview lookup, actual charges, and existing-project integration. Report the result and any concrete limitation; a rendered image does not establish topology quality or provide a 3D viewer.
