So I'm relatively new to the DM side of roll20 and recently I tried to use UDL for the first time (I'd never used Advanced Fog of War up until this point either). It took a long time to set up all the walls on the DL layer but I was pumped to use such an awesome system. When my players loaded in 2 out of 5 of them could see the entire map, including all info and tokens that was supposed to be hidden behind DL lines from their perspective. I had to scrap the entire UDL system and use old fashioned simple Fog of War, which was pretty disheartening. Plus it kind of spoiled a large part of the dungeon. Since then I haven't touched UDL or AFoW with a ten foot pole. I want to try it again so I prepared a new map, but experienced several bugs when testing UDL, such as the token's vision seemingly just switching off randomly. In my frustration I tried the old AFoW system expecting it to be just as bad. To my surprise it was as smooth as butter, and I didn't experience any lag. I browsed reddit and found that some people feel like AFoW is rusty but trusty, and UDL doesn't bring anything new to the table. I guess I'm asking which should I use? Is there a benefit to UDL that I'm not seeing? Any tips on how to use AFoW or UDL effectively? I'm not looking for a rant at the devs about this or that, I just want what's best for my game. Thanks!
