Generate 3D models from images using Hunyuan3D v2 and Google Sheets
VerifiedAutomates 3D model generation from Google Sheets image URLs via Hunyuan3D v2.
What this workflow does
The workflow reads image URLs from Google Sheets, initiates 3D generation through HTTP calls to the Hunyuan3D v2 endpoint, loops status checks until completion, and updates each row with the resulting .glb asset link.
It serves artists, game developers, and e-commerce teams who need to batch-convert 2D images into 3D models without manual API handling or file management.
Who is this for?
3D artists, game developers, e-commerce teams, and AR/VR creators who regularly convert 2D images into 3D assets and track results in spreadsheets.
What problem it solves
Manually generating 3D models from images is slow and repetitive. This workflow automates the full pipeline from Google Sheets image URLs through Hunyuan3D v2 on Fal.ai to saving .glb links back in the sheet.

What it automates
Game Development
Turn concept art into prototype props and assets by feeding image URLs from a shared sheet and retrieving ready-to-use .glb files.
E-commerce
Convert product photos into interactive 3D models for web viewers without leaving your existing product data spreadsheet.
AR/VR
Batch-generate background assets from 2D references and store the downloadable links directly in Google Sheets for quick import.

How to set up Generate 3D models from images using Hunyuan3D v2 and Google Sheets
- 1Create a Google Sheet with columns IMAGE_URL and RESULT_GLB and add your image URLs.
- 2Sign up at Fal.ai, generate an API key, and create a Header Auth credential in n8n named Authorization with value Key YOUR_API_KEY.
- 3Import the workflow into n8n and select your Google Sheet in the Get new image and Update Result nodes.
- 4Attach the Fal.ai Header Auth credential to all HTTP Request nodes.
- 5Activate the workflow and add new image URLs to the sheet to trigger processing.
How to customize this workflow
- →Change the schedule trigger to a webhook or manual trigger for on-demand runs.
- →Add extra columns in the sheet and update nodes to store additional metadata like generation time.
- →Adjust the 30-second polling interval in the loop node if you need faster or slower status checks.
- →Extend the workflow to download the .glb file locally instead of only saving the link.
