Meshy 6

POST/v1/run

Meshy V6 is Meshy's text-to-3D AI model. Turn written descriptions into textured 3D objects with realistic geometry and materials.

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/text-to-3d.

Default: meshy/meshy-v6/text-to-3d

stringpromptrequired

Describe what kind of object the 3D model is. Maximum 600 characters.

Optional<integer>seed

Seed for reproducible results. Same prompt and seed usually generate the same result.

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<boolean>enable_animation

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

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<boolean>should_remesh

Whether to enable the remesh phase. When false, returns unprocessed triangular mesh.

Default: true

Optional<boolean>enable_pbr

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

Default: false

Optional<integer>target_polycount

Target number of polygons in the generated model

Range: 100 to 300000

Default: 30000

Optional<string>texture_prompt

Additional text prompt to guide the texturing process (only used in 'full' mode)

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<boolean>is_a_t_pose

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

Default: false

Optional<string>symmetry_mode

Controls symmetry behavior during model generation.

Allowed values: off, auto, on

Default: auto

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<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 (only used in 'full' mode)

Optional<string>mode

Generation mode. 'preview' returns untextured geometry only, 'full' returns textured model (preview + refine).

Allowed values: preview, full

Default: full

Response Schema

The submit endpoint returns an accepted generation task. Poll the result endpoint with the returned id for terminal outputs or errors.

Optional<string>error

Error message if the task failed. Empty on success.

stringidrequired

Unique identifier for the generation task.

Optional<string>model

Model ID used for the prediction.

Optional<array>outputs

Array of generated content. Empty when status is not completed.

stringstatusrequired

Status of the task: pending, running, completed, failed, or timeout.

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

Model capabilities

array<string>capability_tagsrequired

Capabilities declared by the model registry.

Default: text-to-3d

stringexecution_moderequired

Execution mode declared by the model registry.

Default: async
