VRay has a hidden render history feature:
The history window seen above is opened by clicking the new H button that appers in the bottom of the VRay VFB after you enable this feature. Every time you save a render from the history dialog it will be added to the list. Images are stored as .vrimg files and include all render elements passes. Double clicking a thumbnail will open the image from the history in the VRay VFB. You need to set the location for the history files, and the file size limit in the options dialog. Older files are removed if you exceed the limit.
WARNING: This feature is not enabled by default because it is not fully developed. Enabling the render history is done at your own risk as there could be bugs present.
To enable the feature you need to add a new system environment variable to Windows.
How to do this in Windows XP:
Click on Start
Right click on the My Computer icon and select Properties
Select the Advanced Tab
Click on the Environment Variables button
Under System click the New button
Create a new variable called VRAY_VFB_HISTORY and set the value to 1
Click OK and close the windows
Start 3ds Max
How to do this in Windows Vista:
Click on Start
Right click on the Computer text and select Properties
Click the Advanced System Settings text on the left
Click on the Environment Variables button
Under System click the New button
Create a new variable called VRAY_VFB_HISTORY and set the value to 1
