What is a "workstation license"?

Workstation license (often shortened to "WS") is a license that may be used on a computer, where the host application (3ds Max, Cinema 4D, ...) is running in "full" mode - with graphical user interface, material editor, and all other features enabled, as opposed to node license.

Workstation licenses are used on computers where a person (designer, modeller, student, ...) is working with the host application to create scenes, apply materials, adjust lighting, etc.

Each workstation license can be also used as a render node license, so having 2 x [1 workstation + 3 render nodes] licenses means that you can use them on 2 workstations and 6 render nodes, but also on 1 workstation and 7 render nodes.
