A custom node for ComfyUI that implements mesh simplification with texture preservation using PyMeshLab. This node allows you to reduce the complexity of 3D meshes while preserving visual quality, and is compatible with ComfyUI-3D-Pack's mesh format.

Mesh Simplifier for ComfyUI

Simplifies 3D meshes with texture preservation using PyMeshLab's Quadric Edge Collapse Decimation algorithm.
    
This node allows you to reduce the complexity of 3D meshes while preserving visual quality and textures.
Works with any mesh from ComfyUI-3D-Pack nodes (StableFast3D, Hunyuan3D, etc.).

- Simplify by target face count or percentage reduction
- Preserves textures and UV maps when possible
- Pre-cleans meshes to fix common issues
- Compatible with textured and non-textured meshes
