The wiper_data unit class is used to define wipers which clear raindrops from the simulated glass panes in the interior view. A separate unit is used for each wiper. They are defined as nameless units, belonging to glass_pane_data via the wipers attribute and are typically included via /def/vehicle/truck/<brand.model>/interior/glass.sui.
|center_bone||string||The name of the bone in the animated interior model's skeleton to use as the wiper's centroid. The bone's Z axis should point 'into' the glass pane (roughly opposite the glass locator's Y axis).|
|length||float||0.0||The length of the wiper 'blade' in meters, along the center_bone's X axis.|
