+---------------------------

+:Type:		boolean
+:Range:		True/False
+:Default:	False
+
+Allow to load additional animation sources when enabled.
+For example, if the main animation mesh has name Meshes/x.nif, an engine will load all KF-files from Animations/x folder and its child folders.
+Can be useful if you want to use several animation replacers without merging them.
+Attention: animations from AnimKit have own format and are not supposed to be directly loaded in-game!
+This setting can only be configured by editing the settings configuration file.
