I'm using roll20 to run a D&D forgotten Realms game at the moment and the question of taking the campaign into Undermountain came up. Now I've got the box set, a scan of the maps and I've run it before at a traditional tabletop. But the scale of transfering even a level of it into roll20 is a bit intimidating. The system warns I might see slowdowns when I stretch a map to even a 1/6th of the full map size. Has anyone ever run Undermountain here on roll20 and if so what did you do for the maps?
