Overview
The Meshy ComfyUI integration lets you call Meshy's Text to 3D, Image to 3D, and Multi-Image to 3D generation directly from a ComfyUI workflow using your Meshy API key.
Installation
Install the Meshy custom node pack through the ComfyUI Manager (search for "Meshy"), or clone the node repository into your ComfyUI custom_nodes folder and restart ComfyUI to load the new nodes.
Adding Your API Key
Generate an API key from your Meshy account settings, then paste it into the Meshy node's API key field or set it as an environment variable, depending on how the node pack is configured. Keep this key private — it is tied to your account's credit balance.
Available Nodes
Text to 3D node — generates a model from a text prompt
Image to 3D node — generates a model from a single reference image
Multi-Image to 3D node — generates a model from multiple reference images of the same object
Each node exposes the same core generation parameters available in the Meshy web app and API.
Common Errors
Authentication errors — usually an invalid or missing API key; regenerate the key if needed
Insufficient credits — the node will fail if your account balance can't cover the generation cost
Timeouts — long generations may exceed ComfyUI's default node timeout; check task status via the API if a node appears to hang
Credits and Output Formats
Generations run through ComfyUI consume credits from your Meshy account exactly as they would through the web app or API. Output models can typically be saved in the same formats supported by the Meshy API (such as GLB, FBX, and OBJ), depending on the node's export options.
FAQ
1. Do ComfyUI generations use the same credits as the web app?
Yes, they draw from the same account credit balance.
2. Why does my node say "unauthorized"?
Your API key is likely missing, expired, or incorrectly entered — regenerate it in your account settings and re-paste it into the node.
3. Can I chain Meshy nodes with other ComfyUI nodes?
Yes, outputs from Meshy nodes can be passed into standard ComfyUI nodes that accept 3D or image assets, depending on the node pack's implementation.
