Questions on Lighting and Line of Sight

I am having some trouble getting dynamic lighting to do what I want it to. Essentially: 1. I want to have a dungeon with torches in it that provide lighting 2. I don't want the players to immediately be able to see the entire map 3. I want the players to have a limited range on the light bubbles they can see I feel as if there is a way to do this, but I can't seem to figure out how. "Enforce Line of Sight" should work, but doesnt. Did I perhaps toggle line of sight to a low number on accident? Is there a way to change it? EDIT: Apparently it was working, after I opened it again, everything was OK. Sorry for the trouble!

Hide the light sources in the GM layer or use Fog of War

Albert, Roll20 can do what you are wanting, so I'm not sure where the problem lies within your game. If all the Dynamic Lighting settings are correct, all of your criteria can be met. My first thought was that maybe you have Global Illumination turned on. But if you have drawn out all your barriers on the Dynamic Lighting layer, then even that shouldn't let the players see everything as long as you also have Enforce Line of Sight enabled. We would need to know more about your game settings before we could try to troubleshoot the problem, I suppose.

Here are the settings I use to achieve those criteria: The first checkbox ("Enabled") activates Dynamic Lighting the second keeps players from seeing through it The third keeps it from updating until they finish their move. (although they could move square by square) The fourth keeps them from moving through walls you have indicated as opaque. The fifth is unchecked so that they must rely on light sources rather than see everything they have Line of Sight on.
