After submission, a task_id will be returned. If you provided a callback_url, when the task status becomes finished or failed, a POST request will be sent to the callback_url.
Regardless of whether callback_url is provided, you can retrieve the result through the unified Query Task Status endpoint.

Meshy 6 3D supports text-to-3D, single image-to-3D, and multi-image-to-3D generation through three public model IDs.

Models

meshy-6-text-to-3d - Generate a 3D model from a prompt
meshy-6-image-to-3d - Generate a 3D model from one image
meshy-6-multi-image-to-3d - Generate a 3D model from 1-4 images

Required parameters

model: meshy-6-text-to-3d, meshy-6-image-to-3d, or meshy-6-multi-image-to-3d
input.prompt: Required for meshy-6-text-to-3d
input.image_urls: Required for image models. Use exactly 1 image for meshy-6-image-to-3d, and 1-4 images for meshy-6-multi-image-to-3d

Optional parameters

mode: Text-to-3D only. preview or full. Default is full
seed: Text-to-3D only. Integer seed for reproducible results
topology: quad or triangle. Default is triangle
target_polycount: Target polygon count. Default is 30000
should_remesh: Whether to enable the remesh phase. Default is true
symmetry_mode: off, auto, or on. Default is auto
should_texture: Image models only. Whether to generate textures. Default is true
enable_pbr: Generate PBR maps such as metallic, roughness, and normal maps
pose_mode: a-pose, t-pose, or an empty string for no specific pose
enable_prompt_expansion: Text-to-3D only. Whether to expand the prompt automatically
texture_prompt: Text prompt to guide texturing
texture_image_url: Image URL to guide texturing
enable_rigging: Whether to rig humanoid characters
rigging_height_meters: Character height used when rigging is enabled. Default is 1.7
enable_animation: Whether to apply an animation preset. Requires rigging
animation_action_id: Meshy animation preset ID. Default is 1001
enable_safety_checker: Whether to enable input safety checking. Default is true
callback_url: Optional webhook URL for task completion notification

Output

The task result may include:

model_glb
thumbnail
model_urls: glb, fbx, obj, usdz, blend, and stl when available
texture_urls: base color and optional PBR texture files
animation_glb and animation_fbx when animation is enabled
rigged_character_glb and rigged_character_fbx when rigging is enabled
basic_animations when rigging is enabled

Each file item includes label, file_url, file_type, format, content_type, file_name, and file_size when available.

Notes

meshy-6-image-to-3d accepts exactly one image in image_urls.
meshy-6-multi-image-to-3d accepts 1-4 images. Images should show the same object from different angles.
The API returns asynchronous task status. Poll the unified task status endpoint or use callback_url.
