Generate 3D models from images using Hunyuan3D v2 and Google Sheets

Description

This workflow automates the conversion of 2D images into high-quality 3D models (.glb format) by integrating *Google Sheets* with the *Hunyuan3D v2* model on *Fal.ai*. It handles the entire pipeline—from fetching image URLs to polling for completion and saving the final asset—eliminating manual modeling time for artists and developers.

How it works
This template operates on a schedule to process images in batches or individually:
Data Retrieval: The workflow fetches new rows from a Google Sheet where the RESULT_GLB column is empty.
AI Generation: It sends the IMAGE_URL to the Hunyuan3D v2 API on Fal.ai to initiate the 3D generation process.
Status Polling: The workflow automatically enters a loop, checking the job status every 30 seconds until the model is marked "COMPLETED."
Result Update: Once finished, it retrieves the download link for the .glb file and writes it back to the specific row in your Google Sheet.

Use Cases
Game Development:** Rapidly create prototype props and assets from concept art.
E-commerce:** Convert product photos into 3D models for web viewers.
AR/VR:** Generate background assets for immersive environments from simple 2D inputs.

Setup steps
Google Sheet:
Create a new sheet with two header columns: IMAGE_URL and RESULT_GLB.
Add the images you want to convert in the first column.
Fal.ai Credentials:
Sign up at Fal.ai and generate an API Key.
In n8n, create a Header Auth credential with the name Authorization and value Key YOUR_API_KEY.
Configure Nodes:
Update the Get new image and Update Result nodes to select your specific Google Sheet.
Ensure the HTTP Request nodes are using your Fal.ai Header Auth credential.
