keithcurtis said: Fog of War is not dynamic lighting. It is essentially a manual mask you place over the tabletop. You can remove bits of it with the reveal tool (in the left hand toolbar). But it does not auto-update as a player token moves. The default when you turn on Fog of War is to obscurre the entire map. You must manually clear areas for the players to see. oh, that would be why, thank you for letting me know.
