You can set the following preferences in the Application category of the Preferences window.
If you are not sure whether you are using a network license or a standalone license, you can check your license type in the Product License information window via Help About MotionBuilder, and in the About MotionBuilder window, click Product License information.
A network license is reclaimed by the license server if MotionBuilder is idle on a computer for more than the timeout period defined in the MotionBuilder Application preference settings. The default idle time (or timeout) period is set to 15 minutes. The timeout period reflects the license timeout period whose minimum value is the timeout period configured by the license server (.opt file).
If you lose your license because of the idle timeout, MotionBuilder attempts to claim a new license once you use the product again. If no license is available, a dialog is displayed enabling you to save your work in progress before MotionBuilder shuts down.
To set up a license server, see MotionBuilder Installation and Licensing.
To enable and set the network license timeout, the adskflex.opt file needs to reside in the same folder as the network license file and the network license requires to be set up to handle license sharing.
Refer to the Lost network license behavior topic in the MotionBuilder Installation and Licensing help.
