Toolkit 2 - Photometric Lights

Starting with this interior scene after downloading the appropriate .IES file, create some photometric lights from the Arnold tab.

Apply the .IES file to the light and then position it to where the light should be coming from. After that, duplicate the light to the next position, then duplicate both lights to the opposite side of the room. This creates all 4 lights needed.
