Meshy T2.5 is Meshy's latest Smart Topology model. It converts a single image into a clean, triangle-only 3D mesh with natively separated parts, with a target polycount of up to 30,000 triangles (default 15,000). Compared with Meshy T2, it produces sharper detail and keeps shape and proportions closer to the input image, at the cost of longer generation times; optional textures, PBR maps and humanoid rigging are supported.

About

Convert an image to a clean, triangle-only 3D model with Smart Topology T2.5.

1. Calling the API#

Install the client#

The client provides a convenient way to interact with the model API.

npm install --save @fal-ai/client

Migrate to @fal-ai/client

The @fal-ai/serverless-client package has been deprecated in favor of @fal-ai/client. Install the new package and update your imports — see client setup.

Setup your API Key#

Set FAL_KEY as an environment variable in your runtime.

export FAL_KEY="YOUR_API_KEY"

Submit a request#

The client API handles the API submit protocol. It will handle the request status updates and return the result when the request is completed.

import { fal } from "@fal-ai/client";

const result = await fal.subscribe("meshy/t2.5/image-to-3d", {
  input: {
    image_url: "https://v3b.fal.media/files/b/zebra/3osHJDI8IZ2wl6sGtEUeB_image.png"
  },
  logs: true,
  onQueueUpdate: (update) => {
    if (update.status === "IN_PROGRESS") {
      update.logs.map((log) => log.message).forEach(console.log);
    }
  },
});
console.log(result.data);
console.log(result.requestId);

2. Authentication#

The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.

API Key#

In an environment where you cannot set environment variables, you can configure the API key manually on the client.

import { fal } from "@fal-ai/client";

fal.config({
  credentials: "YOUR_FAL_KEY"
});

Protect your API Key

When running code on the client-side (e.g. in a browser, mobile app or GUI applications), make sure to not expose your FAL_KEY. Instead, use a server-side proxy to make requests to the API. For more information, check out our server-side integration guide.

3. Queue#

Long-running requests

For long-running requests, such as training jobs or models with slower inference times, it is recommended to check the Queue status and rely on Webhooks instead of blocking while waiting for the result.

Submit a request#

The client API provides a convenient way to submit requests to the model.

import { fal } from "@fal-ai/client";

const { request_id } = await fal.queue.submit("meshy/t2.5/image-to-3d", {
  input: {
    image_url: "https://v3b.fal.media/files/b/zebra/3osHJDI8IZ2wl6sGtEUeB_image.png"
  },
  webhookUrl: "https://optional.webhook.url/for/results",
});

Fetch request status#

You can fetch the status of a request to check if it is completed or still in progress.

import { fal } from "@fal-ai/client";

const status = await fal.queue.status("meshy/t2.5/image-to-3d", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
  logs: true,
});

Get the result#

Once the request is completed, you can fetch the result. See the Output Schema for the expected result format.

import { fal } from "@fal-ai/client";

const result = await fal.queue.result("meshy/t2.5/image-to-3d", {
  requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);

4. Files#

Some attributes in the API accept file URLs as input. Whenever that's the case you can pass your own URL or a Base64 data URI.

Data URI (base64)#

You can pass a Base64 data URI as a file input. The API will handle the file decoding for you. Keep in mind that for large files, this alternative although convenient can impact the request performance.

Hosted files (URL)#

You can also pass your own URLs as long as they are publicly accessible. Be aware that some hosts might block cross-site requests, rate-limit, or consider the request as a bot.

Uploading files#

We provide a convenient file storage that allows you to upload files and use them in your requests. You can upload files using the client API and use the returned URL in your requests.

import { fal } from "@fal-ai/client";

const file = new File(["Hello, World!"], "hello.txt", { type: "text/plain" });
const url = await fal.storage.upload(file);

Auto uploads

The client will auto-upload the file for you if you pass a binary object (e.g. File, Data).

Read more about file handling in our file upload guide.

5. Schema#

Input#

image_url string* required

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.

target_polycount integer

Target number of triangles in the generated model. Smart Topology output is triangle-only. Default value: 15000

should_texture boolean

Whether to generate textures Default value: true

texture_model TextureModelEnum

Model that textures the generated mesh, in the same task. 'default' uses Meshy's default texture model for T2/T2.5 (Meshy 7). Ignored when should_texture is false. meshy-n1 makes a 2K base color texture from reference images only: it rejects texture_prompt and enable_pbr. With meshy-n1, texture_image_url is used as the front view, or the input image when it is unset. Default value: "default"

Possible enum values: default, meshy-7, meshy-n1, meshy-6-lite

enable_pbr boolean

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

pose_mode PoseModeEnum

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

Possible enum values: a-pose, t-pose,

texture_prompt string

Text prompt to guide the texturing process. Maximum 800 characters.

texture_image_url string

2D image to guide the texturing process

enable_rigging boolean

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.

rigging_height_meters float

Approximate height of the character in meters. Only used when enable_rigging is true. Default value: 1.7

enable_animation boolean

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

animation_action_id integer

Animation preset ID from Meshy's library. Only used when enable_animation is true; in that case it must be in [0, 696]. See https://docs.meshy.ai/en/api/animation-library for available action IDs. Default value: 92

enable_safety_checker boolean

If set to true, input data will be checked for safety before processing. Default value: true
