sourceless, uniform dim light?

My players are outside in moonlight. I want the area to be illuminated, but not by bright light, and I don't want that light to be inside the buildings. A token with dim light has a pretty harsh gradient, and the light should be uniform and have no obvious source. Is there a way to do this? I tried playing with the new dynamic lighting and everything got much worse. Not interested in any solutions involving that system until they've figured it out a bit more.

You can play around with a weird quirk in the Legacy Dynamic Lighting system to maybe achieve what you are looking for. Set up a token on the Object or Lighting Layer. Set that token's Emits Light settings to something like 100 and -100 . It should create an even dim light over a large area. You may need to tweak the numbers some, and with buildings on the map you may need to make multiple copies of this token and position them around to get the overall effect. Other users have placed an invisible token or a token like a tree or a chair on the Object Layer and given it a large light gray aura that covers the map. Edit: Though the aura would go inside the buildings, too. I forgot about that.

I went with the 100/-100 thing for lack of a better solution. Unfortunately, it isn't uniform, it creates shadows, and if any of them overlap they add together. Better than nothing but not ideal.

What I'd really like is just to be able to draw a rectangle over an area and say "this area is dimly lit", similar to the way you can draw hidden areas if you aren't using dynamic lighting.

You'll have to fix it later, but give everyone darkvision at 100, 1.  It does get gradually darker, but way out, it actually feels kind of natural.

Yeah, there are no perfect solutions at the moment. :-/ Roll20's plan is that the Updated Dynamic Lighting in beta testing now will eventually allow development for lots of neat lighting effects and features like this.
