Account Tab
This tab shows the status of your OctaneRender® license. You may release the license by using the Sign out button or alternatively from Standalone, which will then free up the license for use on another computer. This operation is only necessary when you are in OFFLINE mode; otherwise, Cinema 4D will deactivate the license upon normal program exit.
For a detailed explanation regarding Octane credentials go to the Deactivation and Troubleshooting topic.
