Hi, everyone, my package <FogOfWar For RTS> now is available on asset store : http://u3d.as/content/shallway/fog-of-war-for-rts only $15 Features *Supports more than 300 clients with good performance! *Use height map to block visible area. *Use multi thread to save performance. needs Unity Pro, and currently is not compatible with Anti-Alias. FAQ: 1, why the height block is not working for my game? try to increase FOW Texture Quality. if still not work, try to add extra wider colliders to specify the block area.
