I havent done much this update, but thought I should have the latest version up. This update is primarily just touching up the fog of war, it is now blocked by trees and cliffs (and any other high objects). The ambient occlusion was also changed, not sure if its an improvement. And theres been a ton of code cleanup to get the fog of war code into something that would be more easily plugged into a new project.
If you want to build an RTS of your own, Elgar’s Code Musings is a decent place to start, he’s written up his findings while developing an RTS in Unity.
