## Description

Export from Blender 5.2 with verified presets - Roblox (FBX/glTF, cages, R15, SurfaceAppearance), Unity (FBX, Humanoid), Unreal (FBX skeletal, Nanite, UCX), Godot/web (GLB, meshopt/Draco, WebP), USD. Scale/axes, smoothing, tangents, leaf bones, clips, batch export, post-export verification. Use whenever an asset leaves Blender.

# Export Pipelines

The execution model is in `blender-core`. Run `blender-asset-qa` (and `blender-game-optimization` for budgets) **before** exporting.

## One call
```
scripts/export_asset.py -- --preset unreal_skeletal --objects SK_Hero --out //export/SK_Hero.fbx
scripts/export_asset.py -- --preset web --collection Export --out //export/scene.glb
scripts/export_asset.py -- --preset unity --objects SM_A SM_B SM_C --batch --out //export/x.fbx   # one file each, at origin
```
Presets: `roblox`, `roblox_gltf`, `unity`, `unity_skeletal`, `unreal`, `unreal_skeletal`, `godot`, `web`, `gltf`, `usd`. Pass any exporter kwarg with `--set key=value`. Every preset is tested with a round-trip that keeps scale and avoids a 100× armature scale.
