Welcome to a step-by-step guide on how to use the ComfyUI-3D-Pack to make 3D asset generation a breeze! This extensive node suite enhances ComfyUI, allowing it to process various 3D inputs using advanced algorithms and models. Whether you want to create stunning 3D meshes or apply textures, this pack simplifies the process to make it efficient and convenient.

Installation Guide

To get started with ComfyUI-3D-Pack, follow these steps for installation:

• Install directly from the ComfyUI-Manager.
• You can also check out the pre-built versions available for Windows 10/11 and Ubuntu 22.04 at this link.
• Run install.py to automatically download all pre-builds according to your runtime environment.
• If automatic builds fail, consider checking the build script.
• If certain nodes are missing, you can click Install Missing Custom Nodes.
• For manual model downloads, place them in the Checkpoints directory, ensuring you do not overwrite any existing .json files.
• Make sure to install Visual Studio Build Tools for Windows and the required packages for Linux as specified.

Generating 3D Assets

Once you have installed the ComfyUI-3D-Pack, you can start creating 3D assets! Let’s use an analogy to understand how the code facilitates this process:

Think of generating 3D assets like baking a cake. Each step requires specific ingredients (data), processes (algorithms), and timing (execution) to create a delicious outcome (3D asset). Here’s how it works:

• Ingredients: Just as you gather flour, sugar, and eggs for cake baking, gather your input files like Mesh, UV Texture, etc., for 3D asset creation.
• Mixing: Your mixer is like the algorithm being used, such as 3DGS or NeRF, which combines these inputs to form the mixture (3D representation).
• Baking: The baking time represents the processing phase, where your data is transformed through various computational steps into a 3D object. This is where models like InstantMesh and TripoSR come into play.
• Decoration: Finally, you add icing and toppings, akin to applying textures and refining your 3D model, resulting in a visually appealing asset ready for use!

Troubleshooting

Sometimes, things may not go as planned. Here are some troubleshooting tips to assist you:

• If you experience OpenGL errors during the visualization, set force_cuda_rasterize to true on the corresponding node.
• For issues with ComfyUI hanging or starting, refer to the guide on resolving the Code Hangs Issue.
• If your comfy3d cannot download pre-trained models automatically, remember that you can also download them manually and place them in the Checkpoints folder without overwriting existing files.
