Level of Detail : A higher level (slider to the right) displays more of the details of the elements in the scenario but decreases performance.
Show Map View : If the scenario represents a real-world area, an inset will display a map of the surrounding area.
Show Backfaces: Turns backfaces on or off. When you display backfaces, city furniture, trees, and terrain are solid from inside and outside, and the terrain is solid from above and below. When backfaces are off, you can see through these items to the other side.
Show Watermarks : Turns watermarks on or off. A watermark is a static image that overlays the scenario. Watermarks allow a publisher to brand and identify scenarios.
Auto-rotate Camera : Starts spinning the scenario around the current camera point. To stop the spinning, deselect this option.
Drag any edge or corner of the canvas to the desired size.
