The compatibility between Fog of War and hex maps is borderline primitive in its current state. You can either reveal areas using rectangle shapes which is poorly adapted to the angular side of hexes or by using the polygon reveal which snaps to an invisible square grid, basically making it even less adapted to reveal hexes. It would greatly benefit to the hex map users to have a way to reveal maps hex by hex and/or having a tool that properly snaps to the hex map for MAXIMUM REVEAL CAPABILITIES!!! Dunno if this post will gain traction or not but it's time to MAKE HEX MAP TOOLS GREAT AGAIN!! (or at least usable for fog of war)
