Meshy T2 is Meshy's faster Smart Topology model. It generates a clean, triangle-only 3D mesh with natively separated parts from a text prompt, with a target polycount of up to 15,000 triangles (default 4,000). Preview mode returns the untextured mesh, and full mode textures it with Meshy 7.1; it generates faster than Meshy T2.5, which suits low-poly assets.

About

Generate a clean, triangle-only 3D model from text with Smart Topology T2.

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/text-to-3d", {
  input: {
    prompt: "A rustic, antique wooden treasure chest with a curved, domed lid, reinforced with dark iron bands and a large circular lock plate on the front."
  },
  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/text-to-3d", {
  input: {
    prompt: "A rustic, antique wooden treasure chest with a curved, domed lid, reinforced with dark iron bands and a large circular lock plate on the front."
  },
  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/text-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/text-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#

prompt string* required

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

mode ModeEnum

Generation mode. 'preview' returns untextured Smart Topology geometry only, 'full' also textures it (preview + refine). Default value: "full"

Possible enum values: preview, full

seed integer

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

target_polycount integer

Target number of triangles in the generated model. Smart Topology output is triangle-only. Default value: 4000

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,

enable_prompt_expansion boolean

Whether to enable prompt expansion. This will use a large language model to expand the prompt with additional details while maintaining the original meaning.

texture_prompt string

Additional text prompt to guide the texturing process (only used in 'full' mode). Maximum 800 characters.

texture_image_url string

2D image to guide the texturing process (only used in 'full' mode)

texture_model TextureModelEnum

Model for the texturing (refine) step, only used in 'full' mode. meshy-n1 makes a 2K base color texture from texture_image_url, which it requires; it rejects texture_prompt and enable_pbr. Default value: "meshy-7.1"

Possible enum values: meshy-7.1, meshy-n1

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

{
  "prompt": "A rustic, antique wooden treasure chest with a curved, domed lid, reinforced with dark iron bands and a large circular lock plate on the front.",
  "mode": "full",
