+The **Terrain Following** option in your [[Game Configuration]] allows you to customize how [[character|characters]] react (specifically, how their vertical position is determined) as they walk across [[tile|tiles]] in the game world. Combining this with the [[collision override]] functionality can provide a variety of behaviors. Read below for more information and visual "side view" examples of each type.
+=====Precise=====
+With this option, the [[character|character's]] vertical position will always follow the terrain geometry exactly. More specifically, the [[character|character's]] position will snap up and down to match any rises and drops in the terrain at their current [[voxel]] coordinate. This type is not recommended for first-person games since it can potentially result in jarring camera movements.

+\\
+=====Smooth (Linear)=====
+With this option, linear interpolation is used to calculate the [[character|character's]] vertical position while moving to the next [[voxel]] coordinate. This means that changes in height from one [[voxel]] coordinate to the next will be smoothed out into a straight-line path and is suitable for games where you want inclines, like stairs, to have linear movement (as if walking up a ramp).

+=====Smooth (Curve)=====
+With this option, the [[https://en.wikipedia.org/wiki/Smoothstep|smootherstep]] function is used to calculate the [[character|character's]] vertical position while moving to the next [[voxel]] coordinate. This is the default setting and provides a good balance between closely following rises and drops in terrain without the sudden snapping up and down that the "Precise" option can result in.
