I just figured out that if you set the start of dim to -1 there's no blotch. It does make it hard to find your ambient source, though. Is there a way to make something invisible to players, but still shed light they can see? Well heck's bells. Nice work, Andrew. Thank you. Those "light bubbles" were making me even more crazy than usual. So +1 to your -1. You have successfully revolutionized my usage ov dynamic lighting, for the better. Now, as to the opacity dimmer? Yes please. Frankly, the pitch black is... well, too pitch black. It breaks immersion to have extremely harsh lines that go from lit--or dimly lit--to absolute zero. Additionally the suggestion to add more light sources... while I'm a huge fan of the person making the suggestion... is, truly not a realistic option for me--and believe me, I tried my best. One of my early dynamic lighting maps has around 40 light sources -- the shadows are still an absolute monstrosity. If I could just put up a dynamic lighting barrier to take the brightness from 100% to 50%, or (enter arbitrary non-zero-value here), my map would have needed around FOUR LIGHTS! (obligatory TNG reference) which would have both saved time and effort, all while providing a superior finished product. I will also save any and all comments about not being able to draw an arc over my curved walls for another post, but believe me, it was madness-inducing at times, as well. In short, combining Andrew L's trick with no dynamic layer barriers and limited lighting radii is as close as I can get to what I am looking for... but now I can't have "natural" lighting barriers, like walls -- so if I use this "mood lighting" my characters can all see through walls by default. I find this is a particularly "argh" point for my campaign development. In brief -- +1, or "please, oh plea-eeease add an opacity slider, controlled by the GM, for the players' dynamic lighting experience. " Thank you.  al e. said: Sometimes I will provide multiple lighting sources, and tuck them onto the GM layer and drop them in or out at need, Great! Got a way to do this without copy/paste? Please share!, When I right-click/layer, I only get 3 options, Map, Token, and GM, layer. I cannot just drop tokens in and out of the dynamic lighting layer, further adding to my "Argh!" factor for creating and managing an immersive experience.
