The Terrain serves as the solid ground that Actors and iProps can stand or move along but not pass through the surface. With the use of Terrain, users have several benefits:

Director Mode:
You may control your actors, animals or vehicles movement along the (terrain) surface just like playing 3D games. Please refer to the Snap To or Follow Terrain section for more information.
Editor Mode:
You may directly place objects right on the terrain, and edit the movement and positioning along the terrain, without the need to worry about making height adjustments.
You are allowed to grow grass or trees on the terrain surface.
It automatically locks the terrain from mouse picking. This prevents you from accidental selection of the terrain or making unwanted changes.
There can be only one terrain per project.
The moving object can not move up a 90-degree angle. It will instead jump to the higher surface abruptly.
Any linking or attach relationship will be removed once the prop is converted to be part of the terrain.
