2. Install 3D Mesh Generation Nodes

Install custom nodes for TRELLIS V2 and Hunyuan3D v2:

Option A: Use ComfyUI-Manager (Recommended)

1. Install ComfyUI-Manager if ComfyUI-Manager is not yet installed.
2. In the ComfyUI web interface, click Manager in the side panel.
3. Click Custom Nodes Manager.
4. Search for and install:
   • ComfyUI-Trellis (TRELLIS V2 Image-to-3D node)
   • ComfyUI-Hunyuan3DWrapper (Hunyuan3D v2 Text/Image-to-3D node)
5. Restart ComfyUI.

Option B: Manual Git Clone

1. Navigate to the custom_nodes/ directory in ComfyUI:

   cd custom_nodes
   git clone https://github.com/JeffreyXiang/ComfyUI-TRELLIS.git
   git clone https://github.com/Tencent/Hunyuan3D-2.git

2. Install requirements for each custom node package.
3. Restart ComfyUI.
