So I emailed the author and he was kind enough to respond and let me know that I simply needed to have the main fog actor and the fog agent components all created by the clients so they exist only client side.
I spent so long making everything in the game REPLICATE and be the SAME I couldn’t get my brain around separating the fog of war so it’s separate for each client. It was actually so easy!
Once I did that, each player now has their own completely independent instance of the fog of war.
So for teams (or alliances between players for example) I will just make all the clients that belong to a team create a fog agent for each unit/building belonging to (or spawned by) any team member.
Thank you again to the author! Great plugin! Saved me lots of work/time.
