Example

from os_fast_ref.api import FastRefAPI

api = FastRefAPI()
api.refresh()

# Default preset
result = api.export_abc_all(output_folder=r"J:\output")
print(f"Exported: {result['exported_count']}, Failed: {result['failed_count']}")

# UE5 — meshes only for all slots
result = api.export_abc_all(
    output_folder=r"J:\output",
    preset="Unreal_UE5",
    abc_options={"ExportMeshes": True, "ExportBones": False},
)

for r in result["results"]:
    status = "OK" if r["success"] else "FAIL"
    print(f"  [{r['slot']}] {r['name']}: {status}")
