Meshy 6 Preview

POST/v1/run

Meshy V6 Preview by Meshy - convert 2D images into 3D models with AI. Generate textured 3D assets from single photos for games, AR/VR, e-commerce, and digital content creation.

Request body

Submit an async generation request. The model field selects the model; other fields are model-specific input parameters.

stringmodelrequired

Model identifier. Set to meshy/meshy-v6-preview.

Default: meshy/meshy-v6-preview

stringimagerequired

Image URL or base64 data URI for 3D model creation. Supports .jpg, .jpeg, and .png formats. Also supports AVIF and HEIF formats which will be automatically converted.

Optional<boolean>enable_rigging

Automatically rig the generated model as a humanoid character. Includes basic walking and running animations. Best results with humanoid characters that have clearly defined limbs.

Default: false

Optional<string>pose_mode

Pose mode for the generated model. 'a-pose' generates an A-pose, 't-pose' generates a T-pose, empty string for no specific pose.

Allowed values: a-pose, t-pose,

Default:

Optional<integer>animation_action_id

Animation preset ID from Meshy's library (500+ presets). Only used when enable_animation is true. See https://docs.meshy.ai/en/api/animation-library for available action IDs.

Default: 1001

Optional<string>topology

Specify the topology of the generated model. Quad for smooth surfaces, Triangle for detailed geometry.

Allowed values: quad, triangle

Default: triangle

Optional<boolean>is_a_t_pose

Deprecated: use pose_mode instead. When true, generates a T-pose model.

Default: false

Optional<boolean>enable_pbr

Generate PBR Maps (metallic, roughness, normal) in addition to base color

Default: false

Optional<boolean>enable_animation

Apply an animation preset to the rigged model. Requires enable_rigging to be true.

Default: false

Optional<string>texture_prompt

Text prompt to guide the texturing process

Optional<string>symmetry_mode

Controls symmetry behavior during model generation. Off disables symmetry, Auto determines it automatically, On enforces symmetry.

Allowed values: off, auto, on

Default: auto

Optional<integer>target_polycount

Target number of polygons in the generated model

Range: 100 to 300000

Default: 30000

Optional<boolean>should_remesh

Whether to enable the remesh phase

Default: true

Optional<number>rigging_height_meters

Approximate height of the character in meters. Only used when enable_rigging is true.

Default: 1.7

Optional<string>texture_image_url

2D image to guide the texturing process

Optional<boolean>should_texture

Whether to generate textures

Default: true

Response Schema

The submit endpoint returns a run response. If its status is pending or running, poll GET /v1/run/{id} with the returned opaque ID until it reaches a terminal state.

stringidrequired

Opaque SandBase run identifier. Use it exactly as returned; no prefix is guaranteed.

stringstatusrequired

Current public run status.

Allowed values: pending, running, completed, failed, timeout

Optional<string>model

Public SandBase model name used for this run.

Optional<array<object>>outputs

Present only for completed runs. Each object is capability-specific; inspect the selected model schema for its fields.

Optional<object>error

Present only for failed or timeout runs. Contains a public error type and sanitized message.

Optional<string>error.type

Stable public error category.

Optional<string>error.message

Sanitized error message safe to show to clients.

Optional<object>usage

Usage details when available.

Model capabilities

array<string>capability_tagsrequired

Capabilities declared by the model registry.

Default: image-to-3d

stringexecution_moderequired

Execution mode declared by the model registry.

Default: async
