Rivermill Studios A storm drain model that slowly emits smoke.
Simply place the asset on your street's road for some additional mood and atmosphere.
The storm drain is a single polygon with an alpha channel (to create the curved corners), allowing it to be effeciently used multiple times in a scene. The steam particle effect has texture sheet animation to create the realistic billowing smoke effect (multiple texture resolutions are included).
The street Skydome is also supplied.
