Hi Brown0,

While I haven’t made a specific Fog of War, this tutorial by Noon was a massive help when dealing with opacity:

I would think that if you take some of the concepts he goes over, you can probably layer a plane with a material that is affected by location based opacity centered around the player’s vision over the map, cutting off areas that are blocked by another actor.
