Nocturnal, without any tinting, narrows the field of vision to the limit set for the distance of the night vision, but the area within that distance is seen as "bright light", not "dim light". I use one of the grey tints to make it "dim light". This seems to work fine. Where I have problems is where one or more of the players (whose characters don't have night vision) have light sources. The light sources overlap creating really bright areas where I can't see anything but white. So, it's not the tinting that causes me problems it's the overlapping light sources. But, I manage because it's all about giving the players the right experience... FWIW, I've seen games on other VTTs. They don't have this problem. It's the way Roll20 implements lighting (and colors) that is the problem. keithcurtis said: Nocturnal does not give dim vision? It should provide dim vision unless dim light already exists in the area, which it brightens to bright. And if tinting is working for you, that's cool. It might be fine if each person has their own tinted vision. But when tints overlap is where tints get wonky. If there is only individual tinted vision and not intersecting tinted light, it should be fine, so long as overlapping tinted visions aren't making an issue for the GM.
