Hello!
I've been working on a tool geared towards map makers to automatically generate dynamic lighting for custom maps for Roll20, Foundry VTT and Fantasy Grounds Unity. It should hopefully make your lives a lot easier when porting custom content to your favorite VTTs, as it should save a lot of time otherwise spent manually tracing the map.
It'll take anywhere from a couple of seconds to a minute depending on the size and complexity, and only requires minimum prep. In the video I perform a test with an 11000 x 14000px map with a mix of caverns and dungeons, courtesy of Midgardia.
Expected release date is early May for patrons at the Dungeon Architect level, but if any patron (of any level) would like early access before release while I finish working on it to test it out, just reach out to me here or on discord.
Cheers!
Nick
