POST/openapi/v1/multi-image-to-3d

Create a Multi-Image to 3D Task

This endpoint allows you to create a new Multi-Image to 3D task. Refer to The Multi-Image to 3D Task Object to see which properties are included with Multi-Image to 3D task object.

Parameters

Name
image_urls
Type
array
Required
Description
Provide 1 to 4 images for Meshy to use in model creation. We currently support .jpg, .jpeg, and .png formats. All images should depict the same object from different angles for best results.
There are two ways to provide each image:
- Publicly accessible URL: A URL that is accessible from the public internet.
- Data URI: A base64-encoded data URI of the image. Example of a data URI: data:image/jpeg;base64,<your base64-encoded image data>.
Name
ai_model
Type
string
default latest
Description
ID of the model to use. Available values: meshy-5, meshy-6, latest (Meshy 6).
Name
should_texture
Type
boolean
default true
Description
Determines if textures are generated. Setting it to false skips the texture phase, providing a mesh without textures.

Applies only when should_texture = true

Name
enable_pbr
Type
boolean
default false
Description
Generate PBR Maps (metallic, roughness, normal) in addition to the base color.
Name
texture_prompt
Type
string
Description
Provide a text prompt to guide the texturing process. Maximum 600 characters.
Name
texture_image_url
Type
string
Description
Provide a 2d image to guide the texturing process. We currently support .jpg, .jpeg, and .png formats.
There are two ways to provide the image:
- Publicly accessible URL: A URL that is accessible from the public internet
- Data URI: A base64-encoded data URI of the image. Example of a data URI: data:image/jpeg;base64,<your base64-encoded image data>
Image texturing may not work optimally if there are substantial geometry differences between the original asset and uploaded image. Only one of texture_image_url or texture_prompt may be used to guide the texturing process. If both parameters are provided, then texture_prompt will be used to texture the model by default.

Name
should_remesh
Type
boolean
default false (meshy-6), true (others)
Description
Controls whether to enable the remesh phase. When set to false, the API returns the highest-precision triangular mesh.

Applies only when should_remesh = true

Name
topology
Type
string
default triangle
Description
Specify the topology of the generated model.
Available values:
- quad: Generate a quad-dominant mesh.
- triangle: Generate a decimated triangle mesh.
Name
target_polycount
Type
integer
default 30,000
Description
Specify the target number of polygons in the generated model. The actual number of polygons may deviate from the target depending on the complexity of the geometry.
The valid value range varies depending on the user tier:
- 100 to 300,000 (inclusive)
Name
save_pre_remeshed_model
Type
boolean
default false
Description
When set to true, Meshy also stores an extra GLB file before the remesh phase completes.

Name
symmetry_mode
Type
string
default auto
Description
The symmetry_mode field controls symmetry behavior during the model generation process.
The valid values are:
- off: Disables symmetry.
- auto: Automatically determines and applies symmetry based on input geometry.
- on: Enforces symmetry during generation.
Name
pose_mode
Type
string
default ""
Description
Specify the pose mode for the generated model.
Available values:
- a-pose: Generate the model in an A pose.
- t-pose: Generate the model in a T pose.
- "" (empty string): No specific pose applied.
Name
is_a_t_pose
Type
boolean
⚠ deprecated
default false
Description
Use pose_mode instead. Whether to generate the model in an A/T pose.
Name
image_enhancement
Type
boolean
default true
Description
Optimizes the input images for better results. Set to false to preserve the exact appearance of the input images without any style processing.
Only supported when ai_model is meshy-6 or latest.
Name
remove_lighting
Type
boolean
default true
Description
Removes highlights and shadows from the base color texture, producing a cleaner result that works better under custom lighting setups.
Only supported when ai_model is meshy-6 or latest.
Name
moderation
Type
boolean
default false
Description
When set to true, the input content will automatically be screened for potentially harmful content. If harmful content is detected, the task will not proceed to generation.
Each image from image_urls and the text from texture_prompt will be screened.
Name
target_formats
Type
string[]
Description
Specifies which 3D file formats to include in the output. Only the requested formats will be generated and returned, which can reduce task completion time.
Available values: glb, obj, fbx, stl, usdz, 3mf
When omitted, all formats except 3mf are generated. 3mf is only included when explicitly specified.
Name
auto_size
Type
boolean
default false
Description
When set to true, the service uses AI vision to automatically estimate the real-world height of the object and resize the model accordingly. The origin will default to bottom unless origin_at is explicitly set.

Applies only when auto_size = true

Name
origin_at
Type
string
default bottom
Description
Position of the origin when auto_size is enabled. Available values: bottom, center.

Returns

The result property of the response contains the task id of the newly created Multi-Image to 3D task.
