Exporting and importing of Light Layer

If you had the ability to export a light layer to a file that could then be uploaded elsewhere, it would allow map creators to share their map files plus the lighting layer without having to create an addon. This would greatly benefit both map creators and users who are seeking to minimize prep time, though I'm not sure if it's something that's possible to achieve.

I believe it is possible. I think you can already possibly do that, if the sender and receiver both have Roll20 Pro account for access to API Mods. The API mod script called "Walls" can recreate Walls in Roll20 from an SVG file. (I am not sure if it can Export roll20 walls to an SVG?). Another script called UniversalVTTimporter also does something like this. Look into those options. I understand the Suggestion is still a valid good suggestion for a built-in Roll20 feature that everyone can access.
