From my (limited) understanding of OSRS, the sprites of an item icon are obtained from the actual object being animated.

Was wondering if this is possible, and if it will yield a different model from simply dropping the item on the ground. Asking this because some items, such as the Archer Ring, give a model without a base when dropped on the ground.
