If you are running the V-Ray license server on a different machine, you need to tell V-Ray where to look for it. This section describes how to do that on each operating system supported in V-Ray for Maya.
Run the V-Ray license client configuration utility from Windows Start > All Programs > Chaos Group > V-Ray for Katana > Licensing > Change license settings.
This will show you the window below, where you can specify the IP address of the machine that is running the V-Ray License Server. Please do not change the connection port that is set by default to 30304.
For example, if the license server machine has IP address of 10.0.0.100, you have to put that address in the License server field, under the tab Primary license server.
Run the setvrlservice program from the /usr/autodesk/maya20##/vray/bin/ directory, e.g:
$ /usr/autodesk/maya2017/vray/binTo do this, run the setvrlservice program from the tools subdirectory in your V-Ray for KATANA installation, e.g:
where [servername or IP] is is the IP address or name of the machine where the V-Ray license server is running, without the the enclosing '[' and ']' characters .
and [server port] is the port used for the license server. The default port is 30304. Note: This setting is per user; if there are many multiple users running V-Ray for KATANA on the machine, you will need to set the license server location for each of them.
