Activating Corona Renderer for Cinema 4D

The "FairSaaS" license for Corona Renderer for Cinema 4D will prompt you to activate automatically or once any Corona rendering is initiated. Please note that you must be connected to the internet for a successful activation. This is a one-time process, and you may choose to disconnect if you wish to work offline in the future.

Activation steps:

1. Download the universal installer (

2. Install Corona Renderer for Cinema 4D on your system.

3. Run Cinema 4D and make Corona Renderer the default renderer. 

4. An activation window should pop up. If it doesn't, press ctrl+r (Win) or cmd+r (Mac) and render a blank scene.

5. Select “Activate FairSaaS/EDU” locate and insert your Customer Zone login information (provided to you in the Customer Zone email earlier).

6. Press "OK" and BAM!! – Your license is now activated.


If you are experiencing any problems with the activation. For example, Corona Renderer does not allow rendering and displays a message such as:

To activate the demo, click on "Activate license" and select "Activate demo for 45 days" and then press "Next". If successful, you should now be activated.

For FairSaaS/EDU activation:

Ensure that you are connected to the internet, and in the licensing drop-down window, select "FairSaaS/EDU" license, then press "Next". You will be prompted to enter your customer zone email and password. Please note that a "demo" license does not require an email or password.

Once successful, you should see a final window pop-up such as:

You should now be all set to continue working with Corona Renderer.

To view your current license status and access additional licensing options, you can go to Corona > About...

Note: The FairSaaS/EDU license will automatically renew each month or year, depending on your license type. Did you know? If you are running an older version of Corona, It is free to upgrade to the latest version, as long as you have an active subscription. Upgrading will not disrupt your license in any way.

How to activate Corona Renderer on a render node

Generally, the installation and activation process is exactly the same on workstations and render nodes so that you can use the above steps. If, for example, your render nodes do not have an internet connection, or they do not have Cinema 4D installed with its UI enabled, please see the following guide:

Activating Corona using the Licensing Server

Environment variable activation

Starting with Corona Renderer 6, it is possible to activate the license using a Windows environment variable. This is intended mainly for specific cases where standard activation methods are not possible. Use this method only if you are sure it is required. Otherwise, it is recommended to use the standard activation steps mentioned above in this guide. 


Variable values:

  • For email and password, use the format “email:password”
  • For licensing server address, use format “LS:address”

NOTE: if you use the "email:password" format, please consider that your login credentials are exposed to anyone with access to the computer!

My license expiration date is wrong!

The "Activated until" date printed in the Corona About window is NOT a date when Corona Renderer will stop working for you. 

It shows a future date at which the license will be automatically extended, provided that the computer is connected to the Internet or visible to the Corona Renderer Licensing Server. Don't worry if that period is shorter than expected - it will get automatically extended anyway.
