ComfyUI itself is a powerful Stable Diffusion workflow tool, and with extensions like ComfyUI-3D-Pack , it can process 3D inputs such as meshes and UV textures and generate high-quality 3D models. Here are some 3D related models that perform well in ComfyUI for scenarios where 3D assets are generated from single images:
Features :
Generate textured 3D mesh from a single image at extremely fast (less than 1 second).
Supports UV expansion and material generation (roughness, metallicity, etc.).
advantage :
High generation efficiency and better material quality than many models.
Performs well on mid-range GPUs like the RTX 3080.
Applicable scenarios : Rapid prototyping, game asset generation.
Installation : With ComfyUI-3D-Pack support, pre-training weights can be downloaded from Hugging Face.
Download : https://stable-fast-3d.github.io/
Features :
High resolution 3D mesh generation supports rapid model construction from single images.
Can be run in stages and is suitable for low-video memory devices.
advantage :
Generate grids are rich in detail and are suitable for high-quality output.
High flexibility and can be combined with NeRF or 3DGS (3D Gaussian spplating).
Applicable scenes : high-detail artistic creation and visualization.
Installation : Model weights are obtained from Hugging Face, and ComfyUI-3D-Pack provides integration.
Download : https://github.com/TencentARC/InstantMesh
Features :
Generate low-poly but high-quality 3D mesh from a single image.
One of the basic models of Stable Fast 3D, which is more efficient after optimization.
advantage :
Low hardware requirements, suitable for beginners or users with limited resources.
The output is easy to edit and optimize.
Applicable scenarios : Simple object modeling, entry-level 3D generation.
Installation : ComfyUI-3D-Pack supports, pre-trained models are easy to download.
Download : https://github.com/VAST-AI-Research/TripoSR
Features :
Generate multi-view images from a single image and convert them to a 3D model.
Compatible with the MVDiffusion model and supports complex object generation.
advantage :
Suitable for scenarios that require consistency of multiple perspectives.
The result can be optimized to a grid or Gaussian splatting.
Applicable scenarios : 360-degree display, animation character design.
Installation : Download the checkpoint file and put it in the corresponding directory of ComfyUI.
Download : https://github.com/SUDO-AI-3D/zero123plus
Features :
Recover 3D shapes from multi-view images, supporting single image expansion to multi-view angles.
Seamless integration with ComfyUI workflows.
advantage :
Strong detail capture ability and suitable for complex structures.
Applicable scenarios : architectural models, industrial design.
Installation : ComfyUI-3D-Pack supports, and the model file needs to be configured manually.

If you are pursuing speed : Stable Fast 3D is the first choice because it is generated for a short time and rich material.
If you need high-quality details : InstantMesh or CRM is more suitable, especially when post-editing is required.
If you have limited hardware : TripoSR and InstantMesh running in stages are ideal.
If you want multi-view generation : Zero123++ provides unique multi-view capabilities.
Install ComfyUI-3D-Pack :
Install directly through ComfyUI-Manager or manually download it from GitHub (https://github.com/MrForExample/ComfyUI-3D-Pack).
Make sure to download the corresponding pretrained model weights and put them in the Checkpoints folder of ComfyUI.
Hardware requirements :
Most models run well on 10GB of VRAM (such as the RTX 3080), and low-video users can try phased workflows.
Workflow optimization :
Use ComfyUI's node interface to adjust parameters (such as viewing angles, materials) for best results.
Combined with tools such as Blender to post-process the generated 3D model.
The “best” 3D model depends on your specific needs. If you are a beginner or seeking to get started quickly, Stable Fast 3D and TripoSR are the best choices for community feedback at the moment; if you are a power user and want to explore more possibilities, InstantMesh or Zero123++ are worth a try. These models are well supported in ComfyUI-3D-Pack.
