With X Outlook, you get a small building in the middle of a wooded area and a small forest. X House is an unusual tree house concept, and the terrain, grass, and stones are in independent sets. X Outlook has the option, through the Posing tab, to hide the roof and walls to locate and view objects, characters, and others inside the house. Finally, it has a Sun-Sky based render setting option, but you can also achieve great things using natural environments in HDRI format.
