When you activate this setting, the exporter removes keys from objects on export if the plug-in determines that the animation has only one key. When two or more keys exist in the file, the keys are exported.
Disable this option to export every key to FBX, regardless of how many are found in the animation.
Sometimes, a file animation contains a single key that is used as a locator. If the single key is not needed, activating this option reduces the file size.
