The Terrain serves as solid ground that Actors and iProps can stand on or move along but not pass through. With the use of Terrain, users have several benefits:
Director Mode:
You may control your actors', animals' or vehicles' movement along the (terrain) surface as if you were playing a 3D game. 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.
The terrain cannot be selected with the mouse. This prevents you from accidentally selecting 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 link or attach relationships will be removed once a prop is converted to become part of the terrain.
