Use when modeling hard-surface objects in Blender (sci-fi panels, props, weapons, vehicles, robots, machined or product parts) with booleans and cutters, bevel modifiers, weighted normals, or subdivision with support loops or creases. Also when shading is broken (smears on flat faces, stretching near a cut, pinching), a bevel shrinks or vanishes after a boolean, a boolean empties the mesh or leaves holes, choosing n-gons vs quads, or making a game-ready mid-poly.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Blender hard surface

Expert hard surface is controlled light on edges: every edge catches a highlight from a bevel or a
support loop, flat faces read perfectly flat, and cuts stay editable until the design is settled.
The experts disagree on method (n-gons and booleans vs quad cages and subdivision), not on the
checks: order of operations, cutter hygiene, planar faces, a shiny matcap orbit. The agent builds
the stack with the toolkit and lets the measurable gates find what a human finds by orbiting. If a
sibling skill named here is missing from your available skills, ask the user to install it
(`npx skills add scenario-labs/skills --skill <name>`); unattended, proceed from tool schemas and
flag the gap.

**REQUIRED BACKGROUND:** scenario-blender-expert (execution channel, review loop, 5.2 API changes).
Toolkit: [`scripts/bx_hardsurface.py`](scripts/bx_hardsurface.py)
(`import sys; sys.path.append("<skills>/scenario-blender-hard-surface/scripts"); import bx_hardsurface as HS`),
world-space meters, stock Blender only.

How to install

The exact contents, by fingerprint
mdr add scenario-labs/skills/scenario-blender-hard-surface@sha256:c02f083b19e38874

The line at the top of this page pins the label git:20261017.88ccf82, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
