Warning, uses experimental package comfy-env to attempt a one click isolated install. Will download and use pixi package manager.

ComfyUI-GeometryPack

Installation

Three options, in order of speed → reliability:

1. ComfyUI Manager (recommended) — search for GeometryPack in the Manager and click Install from the highest version displayed. If that doesn't work, try nightly.
2. Manager via Git URL — in ComfyUI Manager: "Install via Git URL" with https://github.com/PozzettiAndrea/ComfyUI-GeometryPack.git.
3. Manual (most reliable):

   cd ComfyUI/custom_nodes
   git clone https://github.com/PozzettiAndrea/ComfyUI-GeometryPack.git
   cd ComfyUI-GeometryPack
   pip install -r requirements.txt --upgrade
   python install.py
   

Please report any problems you hit during installation or use of my nodes — open a Discussion or Issue. Very grateful for your help! 🙏

Multi-Backend Nodes

Each of these nodes presents a single UI with a backend selector dropdown. Under the hood, ComfyUI's GraphBuilder dispatches to hidden backend-specific nodes, enabling cross-environment execution (main, Blender, GPU, CGAL).

Decimate Mesh	quadric_edge_collapse, fast_simplification, vertex_clustering, cgal_edge_collapse, decimate_pro
Fill Holes	trimesh, pymeshlab, pymeshfix, igl_fan, cgal, gpu_cumesh
