This basic guide explains how to use AI tools to create high quality 3d generated models using Comfyui and Hunyuan3D-2. The installer follows the standard manual install steps to deploy this software on windows using a windows bat file. (scroll down this page to section Installation files to download the bat file which you can run from any dir. But before you run the installer read the guide and do the prerequisites and hardware check.)
The installer sets up a free open-source ComfyUI Portable (portable means it has an embedded python so you dont have to manage any technical python code setup on your pc) install with Hunyuan3D-2 plugin on your local Windows PC. You dont have to do any git, python or technical configuration. The only setup you do is in the local ComfyUI webapp desktop to do final config and update.
Its possible to install on linux/mac with Nvidia using the exact same steps but the script is tested and works for Windows. A converted Ubuntu linux install script is also provided but its untested.
Using this setup, you can quickly generate game-ready placeables, creatures, or tileset parts from either a 2D image or a text prompt, producing fully textured 3D models with UV mapping. The AI intelligently predicts the 3D shape and even generates unseen textures based on the image input. (Check out the example 2d images: Cobra statue, Red Dragonborn and gorilla on a white background and the resulting generated models by Hunyuan3D-2 exported intoBlender.)
Generating a 3D model with textures typically takes 1 to 3 minutes with Nvidia gpu, depending on your chosen quality settings and PC hardware. If you have a 6 GB vram or better Nvidia GPU, you’ll achieve the faster and higher-quality results. However, if you don’t have an Nvidia card, you can use your CPU (slow choice many mins generating) or try an online service.
Hunyuan3D-2 a free Online 3D Model Generation (Hugging Face hosted)
If you prefer an online option, Hugging Face offers a free 3D model generator powered by Hunyuan3D-2, accessible here which has a simple but limted interface:

Below shows source 2d image ready for conversion to 3d. A 2d cobra image placeable statue generated from AI descripton using Google Gemini Imagen3.
Next shows the free online tool Hunyuan3D-2 with imported 2d image (or you could give it an AI text chat description for what you want it to 3d create) and then the generated 3d model with texture button pressed and result.
The result is very similar to the 2d image, whats missing is the gold star on its body. By generating again with another seed number (random starter value) then other variations can be produced.
Click to zoom in:
This online version has a fixed face count of 40K, and while the results can be impressive, they lack the fine-tuned control available in ComfyUI. (40k faces single mesh is too much for NWN).
This simplified generator can also be installed locally but for the effort and features you are better off installing ComfyUI.
Tip: Explore the Advanced Settings section for extra customization options. However, they are still more limited compared to a local ComfyUI installation.

Local ComfyUI vs. Online Services
If you want full control over settings like polygon count, texture resolution, and quality, a local installation of ComfyUI is the best choice. Some third-party providers also offer hosted ComfyUI instances with a pay-per-use model.
On Hugging Face’s free tier, you can generate three models per day before needing to purchase credits. However, if you have a 6GB+ VRAM Nvidia GPU and at least 24GB RAM, you can generate higher-quality 3D models directly on your PC within minutes.
ComfyUI: AI-Powered 3D Model Generation from 2D Images or Text
ComfyUI and its plugin AI model generators like Hunyuan3D-2 allow you to generate 3D models with textures and UV maps from either a 2D image or a text description. The AI intelligently reconstructs the missing parts of the image, creating a fully detailed 3D model ready for import into Blender.

ComfyUI example workflow is accessed as web browser app that connects to a python server application. So it can be installed locally on same pc or as remote service or for easy sharing or deployment.
These screen shots shows the ComfyUI desktop and workflow of the Cobra statue 2d image input top left. The setup workflow is provided so you just load the image and tweak some settings and then press queue button to generate the 3d model.
The workflow spans across three pages and you can drag/move/zoom the canvas to see the workflow. It starts top left and the steps flows to the bottom right where the completed 3d model is shown.
Features & Capabilities
- Polygon Control: Generate models with exact faces count you want from low poly (5K faces) to high poly (250K+ faces).
- Texture Quality: Adjustable texture resolution, supporting up to 2K upscaled and detailed textures.
- Extensive open source plugin eco system: 2d AI image generators, Advanced upscalers, PBR texture generation and many more.

This is a link to an advanced Comfyui with Hunyuan-3d-2 Youtube tutorial. Its excellent as it shows Comfyui in use, It starts with manual install of comfyui (skip that as you can use the installer here) and then the tuturial shows how to improve the model generation quality with a custom workflow to produce much higher quality textures, texture paint in blender, retopologise using quad remesher and then bake the texture to the model to have a lower poly game ready model.

The screen shot of Blender 3D gorilla model shown has 20K faces, which The screen shot of Blender 3D gorilla model shown has 20K faces, which was achieved by splitting the original model into two meshes (top and bottom halves, each with 10K faces) by cropping the 2d image into two parts from the belt: part below is waist and legs, part above is torso, arms and head. This generated two 3d model meshes and was then merged as one model in Blender. This technique is useful optimization for Neverwinter Nights, where the per-mesh face limit is 10K. Also breaking the model into meshes with less to create per part makes it more detailed and easier for the 3d generator limited texture memory.

📌 RAM: 24GB minimum (32GB recommended for multitasking)
📌 GPU: Nvidia GPU with at least 6GB VRAM (8GB–12GB recommended for best performance)
- If you have less than 8GB VRAM, you can enable the low VRAM mode when launching ComfyUI.
- By default, ComfyUI automatically detects available VRAM.
- The installation downloads large AI model files (~50GB total), so a fast internet connection is recommended.

Installation Process (new Windows installer uptodate)
Follow this new guide to install the latest version of comfyui. It also has an easier process and more sophisticated windows installer compared to the bat installer i created below. It automates the same install process but uses a newer version of Comfyui and Hunyuan 3d-2.
The steps I did for a fresh install is to run the installer let to download fully and wait for the message 'all startup tasks have been completed'. then https://github.com/YanWenKun/ComfyUI-Windows-Portable Download the two zip files. Download the models and place in the dir as noted after you run the installer that creates the empty model dirs.
1) copy all the files in dir ExtraScripts to one dir up so you can run_nvidia_gpu.bat to start ComfyUI. (you cant start comfyui with run_nvidia_gpu.bat in the ExtraScripts dir but it works one dir up)
2) Manager button. Press Update Comfyui and restart then refresh the webpage.
3) install two custom nodes using Manager button and Custom Nodes Manager: ComfyUI Hunyuan-3D-2 and ComfyUI-ComfyUI-Hunyuan3DWrapper.
4) In CMD terminal go to root dir and run: .\python_standalone\python.exe -m pip install "Comfyui\custom_nodes\comfyui-hunyan3dwrapper\wheels\custom_rasterizer-0.1.0+torch260.cuda126-cp312-cp312-win_amd64.whl"
5) From Comfyui web interface menu (top left) Workflow/Open to load workflow in the ComfyUI\custom_nodes\comfyui-hunyan3dwrapper\example_workflows\hy3d_example_01.json.
6) Top left on the now loaded worflow open image button and choose the penguin found in the example_workflows dir from the last step you did.
7) Press the blue button RUN located at the bottom of the workflow. Wait a few mins for models to download and the 3d penguin should appear bottom right.
Installation Process (old version)
ComfyUI installation involves five main steps. Follow the steps in order and do not skip any to ensure a successful setup. The install guide details via screenshots every step.
