This system make it so that when an item is dropped, it creates a placeable base on variables set on the item and it is possible to grab back the object by using the player tool. The object don't need to be useable as you can target the ground with your player tool and it let you select an object close to the targeted location. The placeables created by this system are persistent (they remain there after a reset, until someone destroy them or pick them up).

It is all in this ERF: https://nwn.sinfar.net/res_list.php?erf_id=437

1. Create the placeable blueprint
2. Create the item blueprint
