UltraShape Save GLB/OBJ

The finish line. UltraShape Save GLB/OBJ takes the refined_mesh that UltraShape Refine produces and writes it to disk as a real file, so you can open it in Blender, drop it in a game engine, or send it to a slicer. Without it, your sharp new geometry lives only inside the graph; with it, you have an asset.

Despite the name it's format-agnostic - the file_format dropdown covers glb, obj, ply, and stl, which conveniently covers every major downstream destination: GLB/OBJ for engines and Blender, STL for printing, PLY if you want a raw point-mesh interchange. This is the output node from the pack's own example workflow, so it's the one most people end on.

What you set

• refined_mesh - the ULTRASHAPE_OUTPUT from UltraShape Refine. Required.
• output_dir - a subfolder of your ComfyUI output/ folder. Default ultrashape_output, created automatically. Keeps your refined meshes out of the output/ root clutter.
• filename_prefix - default refined. Files get a timestamp and random suffix (refined_20260825_120000_ab12cd34.glb), so you never overwrite a previous run and never have to babysit names.
• file_format - glb (default), obj, ply, or stl.

The output is a file_path string, relative to output/, which is useful if you want to pass it to another node - but since this is an output node, mostly it just means "your file is at ComfyUI/output/ultrashape_output/refined_….glb."

Notes and gotchas

Install is the pack standard:

cd ComfyUI/custom_nodes
git clone https://github.com/jtydhr88/ComfyUI-UltraShape1
cd ComfyUI-UltraShape1
pip install -r requirements.txt

Restart; ComfyUI Manager installs it as ComfyUI-UltraShape1. No weights needed for the save itself - but the Refine node feeding it needs ultrashape_v1.pt in ComfyUI/models/UltraShape/ for the graph to run at all.

One honest caveat: this node saves geometry and geometry only. UltraShape doesn't produce textures, so your exported GLB is a bare mesh - no material, no UV-painted skin. That's not a bug in the saver; it's what the refiner outputs. If you want a textured asset, run the refined mesh through a texturing pipeline first (UltraShape Output To Trimesh is the bridge to Trellis2-style texture nodes) or texture in Blender. Also remember that "refined" is doing a lot of work - the export is exactly what the diffusion produced, potentially hundreds of thousands of triangles. You may want a decimation or retopo pass before it goes into a game engine; the printer, as always, doesn't care.
