Mesh Delete

This is the one node in this cleanup family that actually removes geometry rather than merging or hiding it. It wraps Blender's bpy.ops.mesh.delete operator - the same one behind the X delete menu you'd hit in Blender's edit mode - and unlike most of Avatar Graph's other Mesh_* wrappers, it has one setting that genuinely changes the outcome: type.

What it actually does

Mesh_Delete removes whatever's currently selected in the mesh, and type decides how far the damage spreads beyond the exact selection:

• VERT - deletes selected vertices, and takes any edges or faces built on them along for the ride. The biggest hammer of the five.
• EDGE - deletes selected edges and any faces using them, but leaves the vertices those edges connected to sitting there as loose points.
• FACE - deletes selected faces along with the edges and vertices that aren't shared with anything still remaining.
• EDGE_FACE - deletes edges and faces from the selection but keeps every vertex in place, even ones that end up isolated.
• ONLY_FACE - strips just the face "skin," leaving the underlying edges and vertices behind as a bare wireframe.

Which one you want depends entirely on whether you're trying to punch a hole clean through the mesh (VERT or EDGE) or peel away surface while keeping the wireframe intact (ONLY_FACE). This is deletion in the literal sense - a hole gets left behind unless something else fills it in afterward. If you actually want to simplify a mesh without leaving a hole, you want one of the pack's Dissolve nodes instead, not this one.

The inputs and outputs that matter

• BPY_OBJ (optional) - the mesh with the selection to delete already made.
• type - one of VERT, EDGE, FACE, EDGE_FACE, ONLY_FACE, choosing what gets removed and how much collateral geometry goes with it.

Output is a single BPY_OBJ, the mesh with the selected geometry (and whatever it dragged along) gone.

How to install it

Search Avatar Graph in ComfyUI Manager, or clone manually:

cd ComfyUI/custom_nodes
git clone https://github.com/avatechai/avatar-graph-comfyui
cd avatar-graph-comfyui
python -m pip install -r requirements.txt

then restart. bpy==3.6.0 is pinned in requirements.txt and needs Python 3.10.x specifically - the README's prebuilt Python-3.10 ComfyUI zip works on Windows, a dedicated conda environment (conda create --name comfyui python=3.10) is the reliable route on Mac/Linux. opencv-python, mediapipe, and segment-anything also install, unpinned.

Common issues & troubleshooting

Nothing gets deleted. This node only acts on whatever's currently selected - if a selection step upstream in your graph selected nothing, ran on the wrong object, or hasn't executed yet, there's nothing here for Mesh_Delete to remove. Trace your selection state back before assuming the node is broken.

You got a hole where you didn't want one. That's the difference between delete and dissolve - Mesh_Delete genuinely removes geometry and leaves an opening, it doesn't merge the surrounding faces to seal the gap. If the mesh needs to stay watertight, one of Mesh_DissolveEdges, Mesh_DissolveVerts, or Mesh_DissolveMode is almost certainly what you actually want.

Picked the wrong type and deleted more than expected. VERT in particular is aggressive - deleting a single vertex can take out every face touching it. If you only wanted to remove the face "skin" and keep the underlying wireframe, ONLY_FACE is the narrower option; reach for it deliberately rather than defaulting to VERT out of habit.
