Setting up your Client Machines

  • Updated

Workstations and render nodes are referred to as clients for the purposes of licensing. You must configure each client machine so that it can find the license server and checkout licenses. 

Option 1 - Client License File 

You can configure your client machine using a client file. You will get a client file from our fulfillment team together with your RLM server license file. This simple LICENSENAME-client.lic file contains a single line of the form: 

HOST <hostname> ANY <port> 

where <hostname> is the hostname or ip address of the license server and <port> is the RLM license server port. 

For example, if your license server hostname is myrlmserver and you are using the default port 5053, your client license file would look like: 

HOST myrlmserver ANY 5053 

The client license file should be placed in the license paths shown in the table below on each client machine. 










Please note: The common license paths only apply to product versions purchased after April 20th, 2022, and special builds of C4D R24 and R25. For information about the correct paths for older versions, please contact volume support ( or go to Setting up RLM Server Licenses that do not have the unified ISV. 

If you want to modify the path in which the client license is saved, you can do so by defining an environment variable called MAXON_LICENSEPATH (note that writing the environment variable in capital letters is important). You can specify your preferred path within this variable.  

For information on how to set up environment variables on macOS, please see this thread: 

The method that works best for most Maxon users is the "envpane" one. 

Option 2 - Environment Variables 

You can configure your client machines to find the license server by defining an environment variable redshift_LICENSE (note that the lowercase 'redshift' is important). This environment variable will specify the hostname or ip address of the license server as well as the port number using the syntax port@hostname or port@ip-address. The default port for the RLM server is 5053 but can be customized if necessary (for example to prevent conflicts with other RLM license servers running on the same machine). See Customizing the license server port above for more details.
