TripoSR ComfyUI Workflow Generator

Choose a real TripoSR ComfyUI workflow, download the JSON, copy the install commands, and fix the setup errors that usually block image-to-3D generation.

Workflow JSON downloader

Simple TripoSR workflow

Uses real Flowty TripoSR node classes: TripoSRModelLoader, TripoSRSampler, and TripoSRViewer.

4 nodes Flowty TripoSR only
Input LoadImage image + optional mask
Optional No rembg node Simple workflow skips background removal.
Model TripoSRModelLoader model.ckpt, chunk 8192
Generate TripoSRSampler resolution 256, threshold 25
Output TripoSRViewer exports OBJ preview mesh

Before you queue the prompt

Drag the downloaded JSON onto the ComfyUI canvas, then replace the sample image with your own object image.

What the real Tripo page teaches

Users choose a result first, not a manual first

Tripo Studio's current landing page splits users into two immediate paths: high-detail models for printing and visual art, or smart topology mesh for games and web apps. This ComfyUI page follows the same intent pattern, but for local workflow users: pick the output path, then get the JSON, command, and fix list.

Install command builder

Copy commands for your ComfyUI environment

These commands match the Flowty TripoSR README: clone the custom node, install its requirements, then download model.ckpt into the checkpoints directory.

Troubleshooter

Fix the errors that usually block TripoSR in ComfyUI

Missing TripoSRModelLoader, TripoSRSampler, or TripoSRViewer

The Flowty custom node is not installed, installed in the wrong folder, or ComfyUI was not restarted after install. 

cd ComfyUI/custom_nodes
git clone https://github.com/flowtyone/ComfyUI-Flowty-TripoSR.git
cd ComfyUI-Flowty-TripoSR
pip install -r requirements.txt
Missing RemBGSession+ or ImageRemoveBackground+

The background-removal workflow needs ComfyUI Essentials. If you do not want another dependency, switch to the simple workflow first. 

cd ComfyUI/custom_nodes
git clone https://github.com/cubiq/ComfyUI_essentials.git
cd ComfyUI_essentials
pip install -r requirements.txt
model.ckpt is not listed in TripoSRModelLoader

Download the TripoSR checkpoint and place it under the standard ComfyUI checkpoints directory. Restart ComfyUI after moving it. 

ComfyUI/models/checkpoints/model.ckpt
No module named trimesh, omegaconf, transformers, or skimage

You likely installed requirements into a different Python environment than the one running ComfyUI. Use the ComfyUI terminal Python and reinstall the Flowty requirements. 

python -m pip install -r ComfyUI/custom_nodes/ComfyUI-Flowty-TripoSR/requirements.txt
CUDA out of memory during sampling

Use the low-VRAM preset, keep geometry resolution at 256, close other GPU apps, and reduce the loader chunk size to 4096.

OBJ appears rotated after export

The viewer applies a coordinate transform before exporting OBJ. Check axis orientation again in Blender before final cleanup or game engine import.

FAQ

TripoSR ComfyUI workflow questions

What custom node does this TripoSR ComfyUI workflow use?

The downloadable workflow is based on the community Flowty TripoSR node. Its real ComfyUI node classes include TripoSRModelLoader, TripoSRSampler, and TripoSRViewer.

Where should I put model.ckpt for the workflow?

Download the TripoSR checkpoint from stabilityai/TripoSR on Hugging Face and place model.ckpt inside ComfyUI/models/checkpoints. The workflow loader expects that checkpoint name by default.

Why does the background-removal workflow show missing nodes?

The rembg version uses ImageRemoveBackground+ and RemBGSession+ nodes. If those are missing, install ComfyUI Essentials or use the simple workflow first.

What should I choose for low VRAM?

Start with the simple workflow, keep geometry resolution at 256, and reduce the Flowty TripoSR loader chunk size from 8192 to 4096 before trying background removal.

Is this affiliated with Tripo Studio or Flowty?

No. TriposRai is an independent educational and utility site. The page links to upstream sources so you can verify the official TripoSR model and the community ComfyUI node.
