Dynamic lighting with Fog of War?

Hey folks, I'm building a new campaign, and I've hit a stumbling block. I have used the Dynamic Lighting in the past, and also use Fog of War as well. The difference is, I've never figured out how to use them together. Some of the rooms are lit up, while others are dark. However, I want to keep the lit rooms they haven't explored yet hidden from the players until they open the door or whatnot. When I set up the Dynamic Lighting layer after the Fog of War is set and starting areas are revealed, it turns the whole map into using the light sources. It's like it forced Dynamic Lighting on the whole map, even though I only set the lines up for specific rooms. Sorry if this is confusing, but any help would be appreciated.

To combine DL with Fog of War you do the following: 1) Set up your DL lines 2) Set up your Light sources 3) Turn Fog of War on and cover the entire map with the fog. 4) When players explore clear the Fog of War from the map sections they are exploring.
When I do that, though, it still creates a dynamic lighting on areas that I'm not outlining. It's no problem for the rooms that are dark, but then on the parts of the map that are in bright light, it still has a "line of sight/lighting" look to it, instead of just being competely visible.

I am not quite understanding what you mean, could you post a screenshot illustrating the problem?

Ah I think I might see what you are talking about...correct me If Im wrong. Are you saying areas outside your dynamic light boxes still have dynamic lighting? If so, its because dynamic lighting is over the entire page. its not like fog of war where you can pick places to remove/have it..no way to do "I only want dynamic lighting inside this box". Once you add dynamic light to a map, the entire map is dark other than where you add lights. Think of dynamic lighting like a lightswitch for the page, you turn it on..the entire map goes black, they need lightsources to see while moving around, and the dynamic lighting layer lines are 'walls' that stops their light (not lines to define where dynamic lighting is and isnt on).
That's what I was looking for. Cheers, mate! That's a shame. I guess they'll have to use their imagination.

I'm a little confused. What's a shame? I use fog of war with my dynamic lighting every time and I have no issues. Fog of war overrides light settings, so a lit room /will/ stay hidden until you unfog it, though I also make 'door' line segments on the DL layer to make double-sure no light spills out of the room until I explicitly 'open the door'
As GenKitty says, Fog of War and Dynamic Lighting play relatively well together. It helps to keep areas you don't want your players in just yet a secret, and you can reveal it when you are ready. If you aren't using the "line of sight" feature yet, you might want to check that out as well. I may be misinterpreting what you're looking for, but line of sight helps restrict what the players can see to the visibility of the tokens then control. You should find the "enforce line of sight" check box one the page settings in the dynamic lighting section. Keep in mind that if you are using line of sight, you, the GM, will have complete visibility for all tokens since you essentially control all of them. You can select a token and hit CTRL+L (or CMD+L on a Mac) to restrict yourself to just what that token can see. If I'm completely off the mark for what you're looking for, please feel free to say so. Gauss's suggestion of posting a screen shot might help in that case to describe the specific effect you are looking for or having issues with.
Robert, I think I understand what your issue is. I had a map where the players started outside in an area near a cave. I set up the cave with DL but I wanted the outside area lit up completely because it was day time. So what I did was put a very large light source outside and I named it the "Sun". This way the players could see everything until they went into the cave, because the outside light would only reach so far. Remember you can place a token on the DL layer and set it as a light source and the players will not see it. This way you don't have to actually have a sun on your map as a token.

I did something similar to Hoffman in my last session. PCs started outside a cave, I had a lightsource outside the cave to send dim light as far into the cave as possible (the first bend in the passageway). Fog of war kept players from advancing too far into the cave too quickly.
Hoffman, that's the idea I was looking for. I didn't even think about that. So, trick is, place light sources down of your own to combine them. That made sense. Thanks.
