blender-export skillA
blender-export is agent-read markdown (skill) from max-786/claude-3d-harness: Export Blender scenes to glTF/GLB (web/AR), FBX (game engines), OBJ (universal), USD (VFX pipelines), STL (3D printing). Includes per-format settings, embed/unpack textures, axis conversion, polygon optimization (Decimate), and target-platform validation. Use whenever the user asks to "export this", "save as glTF / FBX / OBJ / STL / USD", "package for Unity / Unreal / Three.js / web / AR / 3D print", or any output format conversion. Make sure to use this skill even if the user does not say "expo.
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Blender Export
Export to the right format with the right settings. Wrong format choice = days of debugging in the target platform.
## Format decision tree
```
Where is this going?
├── Web (Three.js, Babylon.js, model-viewer, AR Quick Look) → glTF / GLB
├── Game engine (Unity, Unreal, Godot)
│ ├── Animated/rigged → FBX (or glTF for modern engines)
│ └── Static → OBJ or FBX or glTF
├── Apple AR (USDZ) → USDZ (special, see Recipe 6)
├── 3D printing → STL (geometry only, must be watertight)
├── VFX pipeline (Maya, Houdini, Nuke) → USD
└── DCC roundtrip → FBX (industry standard)
```
**Quick rule for unknown target**: glTF / GLB. Open standard, modern, universally supported.
## Recipes
### Recipe 1 — glTF / GLB export (web / AR / general)
```python
import bpy
bpy.ops.export_scene.gltf(
filepath='/tmp/output.glb',
export_format='GLB', # single-file binary; preferred
export_apply=True, # apply modifiers before export
export_materials='EXPORT',
export_image_format='AUTO', # PNG; AUTO falls back to JPEG for opaque images
export_yup=True, # Y-up convention (most engines / web expect this)

How to install
mdr add max-786/claude-3d-harness/blender-export@git:20260921.d4bf893mdr add max-786/claude-3d-harness/blender-export@sha256:d226627b03df9daePin 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.
