Chaos provides support and technical assistance to customers for the newest and the previous Chaos product major version.
For example, if the newest V-Ray version is 5, Chaos will support and assist users of V-Ray 5 and V-Ray Next.
Support for all current and previous versions of our software can be found in the Chaos forum.
In some situations the only way to resolve an issue of a previous version of our software is to upgrade to the newest version. You can check the upgrade options available for your subscriptions at My Chaos > Active Products.
