Hiramtan, when you modified the shader for 5.5.0, does the "Image Effect" fog of war work as well? I'm really trying to get the Image Effect part of the asset to work again in Unity version 5.5 and beyond. If so, would you mind sharing what you did to modify the shader?
And ArenMook, if you see this, I know the asset has been deprecated for a long time now, and you're not actively supporting it anymore, but is there any chance you could help me get the Image Effect to work again in 5.5+ (it almost works actually, I feel it just needs a small adjustment somewhere in either the shader or the c# script). I'm also willing to pay you for it, so contact me if you're interested.
Thanks.
