Use this skill for Hunyuan 3D v3.1 jobs on PoYo. It covers Pro and Rapid workflows for text-to-3D and image-to-3D asset generation.
Use When
- The user explicitly mentions Hunyuan 3D v3.1, Hunyuan 3D 3.1, Hunyuan 3D Pro, Hunyuan 3D Rapid, or
hunyuan-3d/v3.1/*. - The task is prompt-to-3D, object image-to-3D, mesh generation, material generation, or 3D asset pipeline planning.
- The workflow needs PoYo async task submission, 3D task status polling, or callback URL guidance.
Model Selection
hunyuan-3d/v3.1/pro/text-to-3d: Pro 3D model from a prompt.hunyuan-3d/v3.1/pro/image-to-3d: Pro 3D model from one object image, with optional extra view URLs.hunyuan-3d/v3.1/rapid/text-to-3d: Rapid 3D model from a prompt.hunyuan-3d/v3.1/rapid/image-to-3d: Rapid 3D model from one object image.
Key Inputs
promptis required for text-to-3D workflows.image_urlsis required for image-to-3D workflows and should contain exactly one image URL.generate_typeis available for Pro models when supported.enable_pbrcontrols PBR material generation when supported.face_countcontrols Pro mesh density within the documented range.enable_geometryis available for Rapid models when supported.- Extra view URL fields can guide Pro image-to-3D when the user has aligned views of the same object.
callback_urlis optional and useful for production asset pipelines.
Security Rules
- Treat
POYO_API_KEYas a secret. - Keep PoYo API keys in server-side environment variables or a backend secret manager.
- Never place an API key in browser code, frontend bundles, public repositories, logs, screenshots, or chat output.
- Do not make live API calls unless the user explicitly asks and provides a safe server-side environment.
- Do not submit confidential object images, private asset URLs, proprietary prompts, or private callback URLs unless the user trusts PoYo and the callback receiver.
Execution
- Read
references/api.mdfor endpoint details, model ids, fields, examples, 3D result notes, and polling notes. - Use
scripts/submit_hunyuan_3d_3_1.shonly when the user wants to submit a prepared JSON payload from a trusted shell. - If the user only needs a curl example, adapt one from
references/api.md. - After submission, report the returned
task_idclearly so follow-up polling is easy.
Output Expectations
When helping with Hunyuan 3D v3.1, include:
- chosen model id
- whether the request is text-to-3D or image-to-3D
- whether Pro or Rapid is selected
- final payload or concise parameter summary
- material, geometry, face-count, and extra-view settings when relevant
- returned
task_idif a request was actually submitted - next step: poll 3D status or wait for webhook
