ComfyUI 3D Engine

Custom ComfyUI setup for 3D generation with Trellis2 + UltraShape pipeline.

Components

• ComfyUI-TRELLIS2: Image to 3D mesh generation (forked with IPC serialization fixes)
• ComfyUI-UltraShape: Mesh refinement using diffusion (forked with mesh handling fixes)
• ComfyUI-3D-Pack: 3D preview and utilities

Key Fixes Applied

ComfyUI-TRELLIS2

• Fixed IPC serialization for isolated subprocess
• Proper torch tensor handling across process boundaries

ComfyUI-UltraShape

• Fixed mesh input handling for list/dict/reference types
• Compatible with Trellis2 subprocess isolation
• File-based mesh transfer for cross-process communication

Setup

1. Install ComfyUI
2. Copy custom_nodes to ComfyUI/custom_nodes/
3. Install Trellis2 isolated environment
