The Terrain Following setting in your Game Configuration allows you to customize how the player character reacts (specifically, how their vertical position is determined) as they walk across 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 examples of each type.

With this option, the player's vertical position will always follow the terrain geometry exactly. More specifically, the player's position will snap up and down to match rises and drops in the terrain at their current voxel coordinate. This type is not recommended for first-person games since it can result in jarring camera movements.

With this option, linear interpolation is used to calculate the player'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.

With this option, the smootherstep function is used to calculate the player's vertical position while moving to the next coordinate. This is the default setting and provides a good balance between closely following rises/drops in terrain without the sudden snapping up/down that the “Precise” option results in.
