Activating Corona Renderer for Cinema 4D


The FairSaaS license of Corona Renderer for Cinema 4D will prompt you to activate automatically or once your start any Corona rendering.

Note: 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 from: https://corona-renderer.com/download/ and install Corona Renderer on your machine.


  2. Prepare your registered email address and your password 

    Your registered email address is the one you entered at the checkout page when buying Corona Renderer from our online store.

    Your password was set by you right after the purchase after following a link in one of the confirmation emails. If you can't find this email, please double-check your SPAM folder and other inbox folders or search your inbox for the keyword "Corona". 

    If you don't remember your password, or if you need to reset it for any other reason, please visit this link. 



  3. Run Cinema 4D and make Corona Renderer the default renderer. To do this, open Cinema's render settings and switch the renderer from ''Standard'' to ''Corona'' and exit the settings.

  4. An activation window should pop up. If it doesn't, press Ctrl+R (Windows) or Cmd+R (Mac) and render a blank scene.

    Note: If you have previously activated the Demo, or any other license, first go to Corona > About and click the "Remove license" button.


  5.  Select “Activate FairSaaS/EDU” and press next. Corona will try to connect to the internet and:

    - If it can connect to the activation server: will prompt for your registered email address and password. Just enter them, click next, and that's all.

    - If it cannot connect to the server (either the computer does not have Internet access, or firewall blocks the connection): you will see your request code along with a link for the offline activation page.
    Visit the link ( https://corona-renderer.com/customer-zone/ ), make sure you are logged in using your registered email address, then input your request code in the "Paste request code" field, and click "Activate FairSaaS". The page will display your activation code. Just copy it back to Corona Renderer activation window, click next, and that's all.


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




Note: To deactivate your current license, go to Corona > About... and press the "Remove license" button. To activate your license again, use the above procedure. This is useful in rare cases, for example when changing the active license type.

 



Troubleshooting:

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 from the licensing options 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. If you're 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 name: CORONA_ACTIVATION

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.
