I often use simple black and white dungeon-layouts like this: If I wish to use light and sight effects, I have to make every single line by my own hands. This takes a ton of time and isnt really precise (blue lines). But it is easy possible to get the contour of such a map and generate a png out of this contour which u can easily lay above ur map (yellow lines). This would work on colored maps too! At the moment roll20 cant use such a png to generate the walls automatically. :-/ But this wonderful feature would be really easy to use and can safe you tons of time! Give me your upvote! Support me for an improved usability of the lighning-feature. :-)
