NyxSceneExporter.__init__(scene, export_folder, cameras=None, lights=None, asset_root_path=None, env_maps=None, light_fields=None)[source]#

Build the Nyx SceneAsset from a Genesis scene.

Runs the full export pipeline (instance / camera / light / env-map / light-field build) immediately; call export_to_file() after construction to serialize the result. Asset side effects (e.g. MJCF / procedural-mesh .obj exports) are written under export_folder during construction.

Parameters:

  • scene (genesis.Scene) – Built Genesis scene to export. All entities with morph.visualization=True and a renderable type are included.

  • export_folder (str) – Directory under __nyx_cache__/ where the scene JSON and any per-vgeom .obj files are written. Must already exist.

  • cameras (list of dict or list of genesis.Camera, optional) – Cameras to write into the scene description. Pass camera-definition dicts (the format produced by NyxCameraSensor.build()) when driving the renderer through Nyx sensors. When None, the scene’s non-debug Genesis Camera objects are exported instead.

  • lights (list of gs_nyx.nyx_py_sdk.LightAsset, optional) – Lights to include. None (default) means no lights.

  • asset_root_path (str, optional) – Root prefix recorded in the scene description for resolving relative asset paths. Defaults to empty string (paths are relative to export_folder).

  • env_maps (list of gs_nyx.nyx_py_sdk.EnvironmentMapAsset, optional) – Environment maps to include. None (default) means none.

  • light_fields (list of gs_nyx.nyx_py_sdk.LightFieldAsset, optional) – Pre-baked light fields to include. None (default) means none.
