Whether you have a Corona for 3ds Max or Corona for Cinema 4D license, you have been migrated to a corresponding Monthly or Annual plan of Corona Premium. This means you have access to Corona 9 which works with both host applications (3ds Max and Cinema 4D), and includes the suite of Chaos tools (Chaos Cosmos, Phoenix, Scans, and Player).
If you would like to change your plan, please contact our support team.
