Trellis is a large-scale AI model designed for generating high-quality 3D assets. It translates text or image prompts into various 3D formats, including Radiance Fields, 3D Gaussians, and meshes. Using the Trellis 3D tool within ComfyUI allows users to create stunning 3D models from standard 2D images. Below is a step-by-step guide to help you navigate this process smoothly. The guide is based on a video posted on Reddit.

Convert 2D Image into 3D Model in ComfyUI Using Trellis 3D
Step 1: Download ComfyUI and Open It
To begin, you need to download ComfyUI. You can find it on the official GitHub repository. Follow the installation instructions carefully to set up the environment on your system. Once installed, launch ComfyUI to access its features.
Step 2: Enable the Trellis Integration
In ComfyUI, navigate to the Custom Node Manager. In the search bar, type “ComfyUI-IF Trellis” to locate the relevant integration. Install and enable this node.
It is crucial to also download the actual Trellis 3D model to ensure the functionality works correctly. To install it, you can check our guide.
Step 3: Upload the ComfyUI Workflow
Next, you will need to upload the ComfyUI workflow that contains all necessary nodes for the transformation process. Download the workflow using the following link: Trellis Workflow. Once downloaded, drag and drop it into ComfyUI or use the upload option.
This workflow includes an image uploader, Trellis model loader mode, Trellis image to 3D node, and a Load 3D node that displays the resulting 3D model. The image uploader will connect to the Trellis image to 3D node, which converts your 2D image into a 3D asset. The Trellis model loader node is essential as it provides the necessary model for the conversion process.
Step 4: Load Your Image
Now that your workflow is set up, proceed to upload the image you wish to convert into a 3D model. This step is crucial as the quality of the input image will directly affect the output.
Step 5: Generate the 3D Model
After loading the image, run it through the Trellis Image to 3D node. However, there is an important point to note: you cannot connect the output of the model file directly to the ‘Load 3D’ node to visualize the output immediately.
To overcome this challenge, you need to save the project by assigning a name to it. When you execute the process, the 3D model will be saved as a GLB file. Once the GLB file is saved, you can manually upload it into the ‘Load 3D’ node. This action will allow you to manipulate and rotate the 3D model, giving you a comprehensive view of the asset you have just created.
