Corona 7 and Older - Basic Licensing Terms
Note: this article applies only to Corona 7 and older!
When you activate Corona Renderer 7 or older, it will registers the license as either a workstation license (where you are working with the 3D viewport, creating materials and whole scenes), or as a render node license (where the computer is used only to render the image without the host application's graphical user interface, usually when doing network rendering). Corona Renderer determines the license type automatically. You do not have to select which kind of license you want to use, and there are no separate activation methods for the workstation and render node licenses.
A workstation license is a license that can be used on a workstation computer (sometimes called a "master" computer), where the host application (3ds Max, Cinema 4D, ...) is running in "full" mode - with its graphical user interface, material editor, and all other features enabled, as opposed to a node license, where the computer is used only for rendering, without the graphical user interface exposed. Workstation licenses are used on computers where you are working with the host application to create scenes, apply materials, adjust lighting, and perform other tasks which require you to actively use the host application. The name "workstation license" is sometimes shortened to "WS". For example, "1WS + 3N" means "1 workstation and 3 render node licenses".
