+----------------
+
+:Type:		boolean
+:Range:		True/False
+:Default:	False
+
+If this setting is true, OpenMW will utilize shield sheathing-compatible assets to display holstered shields.
+
+To make use of this, you need to have an xbase_anim_sh.nif file with weapon bones that will be injected into the skeleton.
+Also you can use additional _sh meshes for more precise shield placement.
+Warning: this feature may conflict with mods that use pseudo-shields to emulate item in actor's hand (e.g. books, baskets, pick axes).
+To avoid conflicts, you can use _sh mesh without "Bip01 Sheath" node for such "shields" meshes, or declare its bodypart as Clothing type, not as Armor.
+Also you can use an _sh node with empty "Bip01 Sheath" node.
+In this case the engine will use basic shield model, but will use transformations from the "Bip01 Sheath" node.
