Hex Crawl Map and Fog of War Question

[cokeb]

I'm running a campaign where my players are about to embark on a journey through an unknown wilderness. I'm running it like a Hex Crawl, and I have set the hex grid to the size I want,

Here's where I'm having trouble: I want the map to be essentially blank in areas they haven't unexplored. I want them to be able to see the hex they're in and all adjacent hexes, and I want any hex they've "uncovered" to remain visible.

Is there an easy way to do this?

You can use the global mask to hide the map and then reveal areas as the party move https://fantasygroundsunity.atlassian.net/wiki/spaces/FGCP/pages/996640166/Working+with+Images+as+the+GM#Global-LOS. You can also turn on lighting and use a single token to represent the location of the party and give it a light source with a radius just big enough to light the hex they are in and the surrounding ones.

In addition to Zacc's links,

Here's the settings I used for a solo game:

And this is my Hexploration demo play:

All you should do is to use the same settings but in the hex map.
Remember to assign size in your measurement system (i.e: 1 hex grid = 40 miles). Check the image under "1- The Toolbox has Wilderness Generator" in above link to see where to enter that.
Size = size of your hex grids in pixels. In case you are gonna fit individual hex pieces.
Distance multipler = is where you should enter the measurement.

You might also find it easier to just "Stamp" the tiles as they explore.
