Loading API documentation
Retexture using Meshy 6 Lite (2k only).
The client provides a convenient way to interact with the model API.
npm install --save @fal-ai/clientThe @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.
Set FAL_KEY as an environment variable in your runtime.
export FAL_KEY="YOUR_API_KEY"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/v6-lite/retexture", {
input: {
model_url: "https://v3b.fal.media/files/b/penguin/DId89qXLu6BXu09RFAwAV_model.glb"
},
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);The API uses an API Key for authentication. It is recommended you set the FAL_KEY environment variable in your runtime when possible.
import { fal } from "@fal-ai/client";
fal.config({
credentials: "YOUR_FAL_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.
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/v6-lite/retexture", {
input: {
model_url: "https://v3b.fal.media/files/b/penguin/DId89qXLu6BXu09RFAwAV_model.glb"
},
webhookUrl: "https://optional.webhook.url/for/results",
});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/v6-lite/retexture", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b",
logs: true,
});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/v6-lite/retexture", {
requestId: "764cabcf-b745-4b3e-ae38-1200304cf45b"
});
console.log(result.data);
console.log(result.requestId);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.
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.
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.
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);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.
model_url string* requiredURL or base64 data URI of a 3D model to texture. Supports .glb, .gltf, .obj, .fbx, .stl formats. Can be a publicly accessible URL or data URI with MIME type application/octet-stream.
text_style_prompt stringDescribe your desired texture style using text. Maximum 600 characters. Required if image_style_url is not provided.
image_style_url string2D image to guide the texturing process. Supports .jpg, .jpeg, and .png formats. Required if text_style_prompt is not provided. If both are provided, image_style_url takes precedence.
texture_resolution TextureResolutionEnumBase color resolution: 2k (2048), 4k (4096), or 8k (8192). 4k and 8k require Meshy 6 or 7. At 8k, PBR maps are 4k and no emission map is generated. Default value: "2k"
Possible enum values: 2k, 4k, 8k
enable_original_uv booleanUse the original UV mapping of the model instead of generating new UVs. If the model has no original UV, output quality may be reduced. Default value: true
enable_pbr booleanGenerate PBR Maps (metallic, roughness, normal) in addition to base color.
enable_safety_checker booleanIf set to true, input data will be checked for safety before processing. Default value: true
