SceneActBench - Reconstruction: leaderboard
Reconstruction task of SceneActBench (2026): 100 3D-FRONT rooms from about 11 calibrated views: build the furnished scene from an empty Blender scene, scored by F-score at 5%. The agent acts through a shared Blender tool interface; task score from 0 to 100, higher is better.
Metric: Task score (0-100): 100 3D-FRONT rooms from about 11 calibrated views: build the furnished scene from an empty Blender scene, scored by F-score at 5%; every configuration drives one headless Blender through the same MCP tool interface (scene and object inspection, Python execution, rendering) with task step budgets; each native geometric error or F-score is mapped to a 0 to 100 case score against a fixed reference, invalid outputs score 0, cases are averaged per task.
