Overview

Sometimes users need to be able to quickly switch between different V-Ray versions without having to constantly reinstall it. In this case, both V-Ray for Nuke and V-Ray Standalone can be installed and run from arbitrary locations on your machine or local network. This page describes how to set up your local system so that it loads the files for the correct version.

The notes here are for the Windows and Linux operating systems only.

 

Unpacking the Contents of the .zip File

Extract the contents of the relevant .zip file into a suitable folder, for example, vray_builds/my_version . After the extraction, there should be four sub folders in it: nuke_plugins, nuke_root, nuke_vray, vray and vray_std .

typeinfo

Previous installations required users to set the VRAY_AUTH_CLIENT_FILE_PATH environment variable to point to a vrlclient.xml file, which contained the V-Ray license server settings. This step is no longer necessary since it is covered when Installing the License Server.
