The V-Ray Scene node is the result of importing a .vrscene file into your scene from the V-Ray Scene Manager. Its parameters are available in the Attribute Editor after import.
Disable – Turns the VRayScene object off in the render. The preview is still visible in the viewport to select the node, but the items in the vrscene do not appear in any renders.
File (*.vrscene) – The path and filename of the vrscene loaded into the Scene node. Animation vrscene can be stored either in one single file, or as a sequence of files with one file per frame. In the latter case, you can use the string <frame0n> in the file name to have it replaced with the current frame number at render time, where n is an integer number specifying the number of digits. For example, if you enter my_vrscene_<frame04>.vrscene as the file name, this will be expanded to my_vrscene_0000.vrscene for frame 0, my_vrscene_0001.vrscene for frame 1, and so on.
Load Mode – Specifies how to load the .vrscene file.
All – Loads the .vrscene file with all its geometry, lights, shading, volumes, etc. Geometry – Loads the .vrscene file with geometry and shading only. This option allows instancing vrscenes using MASH or nParticles. The new scene can be exported as a .vrscene, too. See the Instancing vrscene with MASH/nParticles examples below.

tip
Geometry Load Mode has several advantages:
the instanced scene uses much less memory;
much faster render times;
makes possible of billions of instances of a geometry.
Flip Axis – Controls which axis is used as a vertical - the Y or Z axes for the loaded vrscene. You can choose between:
None – No changes in the axes are applied. Auto – It aligns the vertical axis of the vrscene with the vertical axis in the scene in cases where the vrscene was not exported from Maya. Use the Auto mode when loading a USD file. Flip – Switches the Y and Z axes.
Add Lights – When enabled, the lights from the vrscene is used in the render.
