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.
