Fog of War in a Multi-Level Dungeon

[BVoodoo17]

When moving from one level/map of a multilevel dungeon to another, the players lose visual progress of the areas they explored on the level they just left. In other words, when the players return to a previously explored level, the map is completely black rather than just being covered in the grey fog of war filter. Are we missing something?

Right now I have player line of site, lighting, and player vision and movement enabled, and when moving from one level to another, I drag the players' tokens from the combat tracker to the destination level/map.

This is expected behaviour. If a token leaves a map and moves to another map then it doesn't retain any details of the fog of war from the map it just left. So when it goes back it has forgotten the data and the map is in an unexplored state again.

Appreciate the quick clarification. Any chance there's a way around this?

[Zacchaeus]

Not that I am aware of, no.

There is a community extension on the Forge (https://forge.fantasygrounds.com/shop/items/224/view) that will load/store the FoW data. Be aware of all of the notes listed on the page if you decide to get it.

This might be a resolution you are looking for:

as it saves the FoW/LoS. it is a paid for extension but might do what you are looking at.

If everyone's computer can handle it, would it be possible for you to add each map level as layers to one image, adding an LOS layer for each? You could then just move tokens around to each image and since they'd never leave the image record it would be persistent. Again, the map might be pretty big if you do this so specs become relevant.

Yes, but it won't help FoW, because FoW is kept per image, not per layer. So when you go to the second level your players with have the FoW from the first level.
