blender-modeling skillA
blender-modeling is agent-read markdown (skill) from max-786/claude-3d-harness: Create and edit 3D meshes in Blender — primitives, hard-surface modeling, mesh operators, modifier stacks (Bevel, Subdivision, Boolean, Mirror, Array, Solidify), bmesh-level edits, retopology basics. Use whenever the user asks to "make/model/create/build a 3D object", "shape/sculpt this", "add a cube/sphere/cylinder/etc.", "extrude/inset/bevel this face", "add a modifier", or any geometry-creation request that isn't a wireframe trace. Make sure to use this skill even if the user does not say "mo.

What the file says
# Blender Modeling
Create geometry in Blender via natural language. You emit Python code that the Blender MCP executes; the patterns below cover the common 80%.
## Decision tree
```
What kind of geometry?
├── Hard-surface (vehicles, weapons, architecture, props)
│ → Cube primitive + Bevel + SubSurf modifier stack
│ → See "Hard-surface stack" recipe
│
├── Organic (characters, creatures, plants — block-out only)
│ → Ico Sphere + sculpting (or Voxel Remesh for shape)
│ → For sculpting strokes, redirect: it's gestural, not text-driven
│
├── Architectural / repeating (fences, columns, tile)
│ → Plane/Cube + Array modifier (+ Curve modifier for paths)
│ → See "Array along curve" recipe
│
├── Cylindrical (pipes, columns, bottles)
│ → Cylinder primitive, or Curve + bevel_object
│ → See "Sweep along path" — covered in wireframe-to-3d if needed
│
├── Holes / cuts in existing geometry
│ → Boolean modifier (DIFFERENCE)
│ → See "Boolean cut" recipe
│
└── Quick block-out from primitives only
→ Multiple primitive_*_add calls
→ See "Block-out scene" recipe
```

How to install
mdr add max-786/claude-3d-harness/blender-modeling@git:20260921.d4bf893mdr add max-786/claude-3d-harness/blender-modeling@sha256:787b50ca5ce131ebPin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
