The Maya FBX plug-in has two export workflow presets:
The Autodesk Media and Entertainment preset is the default preset for the Maya FBX plug-in Exporter. The Autodesk Media and Entertainment preset contains the optimal settings for most animation workflows.
The Autodesk MotionBuilder preset is used for exporting animation files to MotionBuilder.Use the Autodesk MotionBuilder preset if you are using a Maya to MotionBuilder back to Maya workflow. This preset uses the Constraints and Skeleton defintions as options set for optimal Character animation using Maya and MotionBuilder.
Choose your preset by selecting it in the menu of the Maya FBX plug-in Presets section.
If you change a preset, the preset field displays User defined, to show that the preset differs from its default state. The plug-in saves the User defined state in a temporary file so that the settings are the default the next time you use the plug-in.
You can also use save your settings as a custom preset. See Creating a custom preset.
