I was looking for a solution too. Thanks a lot! Demi, work time Brian C. said: DungeonMair said: I've uploaded a map of a boat at sea. The boat has four decks, all shown on the map. I've drawn the dynamic-lighting barriers for the boat at every deck level; no external light source will penetrate the hull. I'd like the sea outside the boat to be bathed in seamless dim light. How can I do this? * Obviously, making the map file itself radiate dim light won't work. * Spreading invisible tokens across the map that radiate dim light doesn't work either, because dim light stacks -- gets brighter -- when it overlaps, and light sources radiate light in circles, not squares; I end up with a huge venn diagram of different light intensities. I've spent a couple hours trying to solve this, to no avail. Your advice is appreciated. You have to either use Daylight Mode (at roughly 50%) or set up several low lights in the corners where the radius reaches the boat in the center of the map. Since the main deck of the ship probably should have the same light level as the water, I would lean toward using dim Daylight Mode. If the interior of the boat is supposed to be pitch black, you can also place the lower decks on a different page that has no Daylight Mode. These can then be placed side by side to each other, and you can drag the PC tokens between decks as the PCs move, allowing PCs to be on different decks simultaneously. If this is an underwater wreck, I would just go with Daylight Mode, as the PCs will probably bring a light source anyway. Otherwise, you will need to use multiple low lights at the edges of the map, giving them a radius that reaches the boat in the center. This will result in some minor overlap, and you will need to position lights so they shine into any holes in the hull.
