Have you ever wanted to take your 2D images and bring them to life in 3D? With the “ComfyUI 2D Image to 3D OBJ Integration Workflow“, created by LOVIS, you can now generate 3D models directly from images and integrate them into scenes. This powerful workflow utilizes powerful generative tools like Stable Diffusion and ComfyUI to transform regular photos into interactive 3D objects.

ComfyUI 2D Image-to-3D Object Integration Workflow
Lovis, a 3D designer, has created a powerful workflow in ComfyUI that allows users to generate and integrate 3D objects into 2D images. This powerful workflow combines various AI models and techniques to quickly generate and integrate 3D objects into 2D scenes. The workflow can be adapted for different types of objects and scenes. You can download this workflow at Civitai.
Key Features of the ComfyUI 3D Workflow
1. Image to 3D Model Generation
The ComfyUI 2D Image to 3D OBJ Integration Workflow first uses Stable Diffusion to generate a basic 3D model from the input image. Advanced machine learning techniques allow it to understand the scene and recreate objects in 3D form.
2. ComfyUI Integration
ComfyUI is then used to refine the model. Its intuitive interface enables editing vertices, applying materials, rigging, and lighting. You can pose and adjust the model as desired.
3. Real-time Scene Integration
The final OBJ file produced can now be directly imported into 3D applications and game engines. This allows designers to embed the generated 3D object back into the original image or new scenes.
4. User Friendly Process
The entire workflow is very easy to use. Uploading an image starts the fully automated generation. Basic 3D knowledge is not required. This democratizes 3D modelling for creatives.

Guide on Using ComfyUI 2D Image-to-3D Object Integration Workflow
After watching the tutorial, here are the steps to use this workflow to generate 3D scenes:
1. Setting Up Your Workspace
Before diving into the creation process, ensure you have ComfyUI installed and running. For optimal performance, consider using Google Colab, which provides access to powerful GPUs, significantly speeding up the generation process.
2. Background Generation
The first step in the workflow is creating a suitable background for the 3D object. The SDXL model “Artistic XL” is a good choice for its realistic rendering capabilities. Set up a simple prompt for background generation. Employ an upscaler with high CFG (Classifier-Free Guidance) settings to enhance detail and quality.
3. 2D Object Generation
The next step is to generate the 2D version of the object, which will later be transformed into 3D. Start with a simple scribble or sketch of your desired object. Use the “Product Design” model for object generation. Implement ControlNet Union for versatile control over the generation process.
4. 3D Object Creation
ComfyUI offers two primary methods for transforming 2D images into 3D objects:
- i. ComfyUI 3D Pack
It is a complex setup and offers advanced features for experienced users
- ii. Trip SR Node by MixLab:
It is an easier setup and ideal for beginners which provides quick and efficient 3D object generation
Use Segment Anything to remove the background from the generated 2D object. Input the segmented image into the chosen 3D generation method. Generate the 3D object mesh.
5. Object Integration
The final step is integrating your 3D object into the background image. Place the 3D object in the desired position within the scene. Use various ControlNets with low strength values for fine-tuned control. Use an IP adapter to match the style between the object and background. Employ differential diffusion for enhanced blending and integration results.
Advanced Tips
- Apply the “grow mask with blur” technique for smoother object integration.
- Use EP-Adapter to transfer superior style between object and background.
6. Final Adjustments
Apply denoising to smooth out any artefacts. Make final adjustments to lighting and shadows for realistic integration.
7. Generate Output
Generate the final integrated image. If necessary, perform minor touch-ups or refinements in image editing software.
Benefits of the Workflow
This ComfyUI 3D workflow allows for rapid prototyping and visualization of 3D objects in various environments. Additionally, it enables creators to generate custom 3D assets without extensive 3D modelling skills.
Lastly
With its intuitive interface and accessibility, the ComfyUI 2D Image to 3D OBJ Integration Workflow makes 3D generative design approachable for all skill levels. By following this workflow and experimenting with different settings, you can create stunning compositions that seamlessly blend 3D objects with 2D backgrounds.
