I don’t have any links, though there might be something in the Tutorials or Blueprint section of the forums.

If I were to make a fog of war right now I would create a grid covering the map and reference it when hiding and un-hiding enemy units in the game. You would also use the grid to hide and un-hide the visual effects of the fog of war when units come in and out of range.

There’s a good RTS plugin repository on GitHub that I will be using for my RTS game. It has a lot of important features already implemented. Up to you if you want to implement or just learn from it:
