This page provides information on working with different scene format types.
Overview
Starting with V-Ray 6.1, a new version of the .vrscene format is available. The new version 2 .vrscene format is smaller in size and optimized for more efficient upload. It has features which aim to make it easier for rendering on a machine different from the one it has been exported from. Version 1 format contains only the .vrscene file. A version 2 scene differs from version 1 as it has at least three files - a .vrscene, a .vrdata and a .vrfiles file.
Note that the new v2 .vrscene file is meant to be used only in Chaos Cloud and is not advisable to be used in other cases - the results might be unpredictable.
Scene Format Issues
Mishandling Scene Files
The new version 2 V-Ray scene format consists of multiple files - a .vrscene file, at least one .vrdata file and least one .vrfiles file. If one of the files is misplaced then scene submission may not work correctly. For example, if you copy only the .vrscene file and then try to submit it.
Old Client Apps
If you try to upload a version 2 V-Ray scene with an older Cloud Client app then not all of the scene data would be uploaded to the Cloud. This would result in a failed rendering. "Older Cloud Client apps" in this context are all versions prior to 1.21.
Requesting Old V-Ray versions
If you have requested a specific version of V-Ray for rendering on the Cloud either by editing the .vrscene file or via AppSDK then this version might be too old to support v2 scenes.
