 Only the natural outdoor and service scenes have published preview images. Each has three frames from an existing Blender animation (start, middle, end). We reviewed offscreen MuJoCo screenshots for the indoor, industrial, and urban scenes and omitted them because the simplified simulation geometry and temporary roof hiding did not represent the appearance of the authored worlds well. Their benchmark data remains available. A missing preview is represented as `null` in the index; it is not evidence that the case is absent. The available images are for visual inspection, not evidence of task success.
