Hi Damocles.. I just tried your latst demo.. looks like you are making good progress... this is getting there!

I have one suggestion about the Fog of war.. instead of drawing two terrains, why not apply the fog map in the terrain shader? this ouwld be faster, and sometimes in your method you can see that the fog terrain isnt the same size as the normal terrain.. like on certain mountains you can see it sticking out.
