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 at least one *.vrfiles* file. If any of the files are misplaced, the scene submission may not work correctly. For example, if you copy only the .vrscene file and then try to submit it.

> ⚠️ If you are moving files around, make sure to move .vrscene, .vrdata and .vrfiles together.


### **Old Client Apps**

If you try to upload a version 2 V-Ray scene using an older Cloud Client app, not all of the scene data will be uploaded to the Cloud. This will result in a failed rendering. "Older Cloud Client apps" in this context are all versions prior to 1.21.

> ⚠️ Always make sure that your [Cloud Client App](https://docs-chaos.atlassian.net/wiki/spaces/VCLOUD/pages/126111024) version is up to date.


### **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 - that version might be too old to support v2 scenes.

> ⚠️ Make sure the V-Ray version InfoRenderEngine plugin is listing at least V-Ray 6 Update 1 (6.01.0).
