Springs Cliffs are its only weakspot - because they cant draw what mother nature has, hard edges.. or to counter the reply. The engine certainly can draw those, but they dont are on par with the sweet rolling hills, the sand dunes and beaches.
Thus i propose and present. The Autocliff.
Step1:
To make everybody happy- make it fully optional. Some of the maps have nice mountains.. dont want to destroy that just for progress.
Now we still need to detect the steepest, unreachable regions with the nice stretchy textues.
Step2:
It then creates a poly stripe, and continues subdividing it until a userwanted level is reached.
Step 3. The Polygroups are either extruded inwards or outwards.(Mostly depending on the distance to the ground below).
Step4.
It then grabs into the colour of the map, and togther with the maps detail texture for said cliff.
Step5:
And if there is a single blade of grass on the map, default grasstexture on all triangles with a smaller slope then <<PlaceRandomMagicVarHere>>
