I had been doing stuff on Roll20 for a couple of years now, but only now getting around to using dynamic lighting. I have always had an advanced account (that you need to us DL), but that was mostly so my players would not be pestered by ads.
In my last campaign I refrained from experimenting with it because I was running for mostly masters of the platform, and I did not want to take time to learn as I went with them. I just used Fog of War, which I found functional enough, and pretty nifty. But now that that campaign is done, for the foreseeable future I am going to be doing a campaign with friends I already had. This is a great time to experiment, as the games will be much easier going. I can fuck around without alienating "experts."
The gang is more or less noobish, and when I announced that we would be trying DL out, they were jazzed. We got down to it, and when the time came to go in a cave I did the set up.
I was starting small, just a three or so room complex. As DM your first move is to have the cave walls outlined so vision does not pass through them. You hit all the right buttons in page set up to prepare.
Then when the characters enter you must go into each characters setting and do up how and what they can see. For those with night vision you enter the distance, along with how much of that distance starts to dim after a certain point. Then you do up torch or lantern users (or light spells) depending on those items capabilities. I like to give firelight a nice yellow glow.
this is all me looking from a player's POV, but
I also get to see outlines of the complex
This small-scale experiment was good, as I need to work up to the larger dungeon the campaign is heading for. Everybody loved it, but I guess my goal should be for it to eventually become old hat. Second nature. But it really adds a cool element you would be hard pressed to get on a face-to-face tabletop (without thousands of dollars of equipment).
More experiments to come. But so far so good.
