Meshy-6

by Meshy January 18, 2026

Meshy-6 is a 3D generation model for text-to-3D and image-to-3D workflows. It is built for cleaner geometry, sharper hard-surface detail, low-poly generation, configurable quad or triangle topology, polycount and symmetry control, A/T pose support, and textured outputs with optional PBR materials. It fits game asset creation, 3D printing, and production-oriented 3D pipelines.

API Options

Platform-level options for task execution and delivery.

taskType string required value: 3dInference: Identifier for the type of task being performed

taskUUID string required UUID v4: UUID v4 identifier for tracking tasks and matching async responses. Must be unique per task.

outputType string default: URL: 3D output type.

Allowed values 1 value

outputFormat string default: GLB

Specifies the file format of the generated output. The available values depend on the task type and the specific model's capabilities.

`GLB`: Binary glTF format for 3D models, including geometry, textures, and PBR materials.

Allowed values 1 value

webhookURL string URI

Specifies a webhook URL where JSON responses will be sent via HTTP POST when generation tasks complete. For batch requests with multiple results, each completed item triggers a separate webhook call as it becomes available.

deliveryMethod string default: async

Determines how the API delivers task results.

Allowed values 2 values

: Returns complete results directly in the API response.
: Returns an immediate acknowledgment with the task UUID. Poll for results using getResponse.

PLATFORM

uploadEndpoint string URI

Specifies a URL where the generated content will be automatically uploaded using the HTTP PUT method. The raw binary data of the media file is sent directly as the request body. For secure uploads to cloud storage, use presigned URLs that include temporary authentication credentials.

Common use cases:

Cloud storage: Upload directly to S3 buckets, Google Cloud Storage, or Azure Blob Storage using presigned URLs.
CDN integration: Upload to content delivery networks for immediate distribution.

// S3 presigned URL for secure upload
https://your-bucket.s3.amazonaws.com/generated/content.mp4?X-Amz-Signature=abc123&X-Amz-Expires=3600

// Google Cloud Storage presigned URL
https://storage.googleapis.com/your-bucket/content.jpg?X-Goog-Signature=xyz789

// Custom storage endpoint
https://storage.example.com/uploads/generated-image.jpg

The content data will be sent as the request body to the specified URL when generation is complete.

ttl integer min: 60: Time-to-live (TTL) in seconds for generated content. Only applies when outputType is URL.

includeCost boolean default: false: Include task cost in the response.

numberResults integer min: 1 max: 4 default: 1: Number of results to generate. Each result uses a different seed, producing variations of the same parameters.

Inputs

Input resources for the task (images, audio, etc). These must be nested inside the inputs object.

inputs » referenceImages referenceImages array of strings items: 1: List of reference images (UUID, URL, Data URI, or Base64). Used to guide the texturing process.

inputs » images images array of strings min items: 1max items: 4: Array of image inputs (UUID, URL, Data URI, or Base64). For single image-to-3D, provide 1 image. For multi-image-to-3D, provide 2–4 images.

Generation Parameters

Core parameters for controlling the generated content.

model string required value: meshy:meshy@6

Identifier of the model to use for generation.

positivePrompt string max: 600

Text prompt describing elements to include in the generated output.

Settings

Technical parameters to fine-tune the inference process. These must be nested inside the settings object.

settings » autoSize autoSize boolean default: false: AI-based real-world height estimation to resize the model accordingly.

settings » decimation decimation integer

Adaptive decimation level.

Allowed values 4 values

: Ultra polycount.
: High polycount.
: Medium polycount.
: Low polycount.

settings » hdTexture hdTexture boolean default: false: Base colour texture at 4K (4096×4096) resolution. PBR maps are always generated at 2K regardless.

settings » imageEnhancement imageEnhancement boolean default: true: Input image optimization for better generation results. Set to false to preserve the exact appearance of the input.

settings » meshType meshType string default: standard: Mesh generation type for the output 3D model.

Allowed values 2 values

settings » moderation moderation boolean default: false: Input content screening for potentially harmful material before generation proceeds.

settings » origin origin string default: bottom: Origin point position for the generated model.

Allowed values 2 values

settings » pbr pbr boolean default: false: PBR map generation (metallic, roughness, normal) in addition to base colour. Includes an emission map.

settings » polyCount polyCount integer min: 100 max: 300000 default: 30000: Target polygon count. Actual count may deviate based on geometry complexity.

settings » pose pose string default: none: Pose preset for the generated model.

Allowed values 3 values

settings » remesh remesh boolean default: false: Remesh phase toggle. When false, returns the highest-precision triangular mesh without decimation.

settings » removeLighting removeLighting boolean default: true: Highlight and shadow removal from the base colour texture, producing a cleaner result for custom lighting.

settings » symmetry symmetry string default: auto: Symmetry behaviour during generation.

Allowed values 3 values

settings » texture texture boolean default: true: Texture generation toggle. When false, returns a mesh only.

settings » texturePrompt texturePrompt string max: 600: Additional text prompt to guide the texturing process.

settings » topology topology string default: triangle: Mesh topology for the output model.

Allowed values 2 values

taskType string required value: 3dInference: Type of the task.

taskUUID string required UUID v4: UUID of the task.

seed integer: The seed used for generation. If none was provided, shows the randomly generated seed.

cost float: Task cost in USD. Present when includeCost is set to true in the request.

modelUUID string required UUID v4: UUID of the output 3D model file.

modelURL string URI: URL of the output 3D model file.

modelBase64Data string: Base64-encoded 3D model file data.

modelDataURI string URI: Data URI of the output 3D model file.
