The Ground Scale Timeline controls the size and appearance of textures and the size and rotation of any image maps applied to the ground.
All settings are grouped in a single dialog which will appear when a timeline is created or edited. The dialog shows the timeline extent and the scale in three axes of the Ground in current units.
Bouncy - Scale values interpolate using either a linear or quadratic rule with on being quadratic. The quadratic method can give a smoother looking effect, but in some cases it can get quite bouncy.
The Delete button deletes the timeline.
The Reset button sets all scale values to unity.
The Store button copies the scale values to a temporary buffer for use later.
The Set button sets the scale values those previously stored.
