How to run Mordheim on Roll20? Tackling the issue of elevation + more

So, I talked to some friends about the prospect of running a Mordheim (or Wyrdwars, or something similar) tactics game, and after some debate it seems like a possibility. We're long distance friends, so this means using Roll20. But given that Mordheim and similar tabletop games are heavily impacted by the use of the environment for, like, EVERYTHING... Well... I'm worried. For one, elevation is huge in Mordheim. Sometimes you'll have multistory buildings where people are fighting on all the floors, battling their way to the top for some objective or the like. Other times elevation matters because someone camped way on high has a clear line of fire at the people down below, and you need to climb up to reach him; or you're running underneath a bridge so the sniper can't kill you from his nest. People leap off high terrain for leaping attacks, people enjoy cover from any bit of terrain against shooters, and... Etc. Building the map is one of the great experiences of Mordheim, and using it to your advantage (or just using it in hilarious ways) is a joy. But how can I make this translate this well to Roll20? Elevation specifically seems like a rough topic. I can do calculations to measure the distance of an archer to someone on a lower elevation, but if you want tall buildings how do you handle tokens being on multiple levels of the same area? Should I just use multiple maps? And if I use multiple maps, is there a way to allow players (people who I might be playing against, or just GMing for) to swap between the maps as if they were a GM? Would dynamic lighting be a useful tool as far as simulating cover mechanics and the like? In every game I've played in on Roll20 the character tokens have been restricted to standing inside a square. Are there other shapes I can use, such as hexes? And is it possible to just give up tiles entirely to allow more free-form character placement? And in general, has anyone tried anything similar to this, and does anyone have any advice? Thanks for any answers I may receive, and thank you for reading this even if you don't have any suggestions.

Some answers, though I don't have any advice on Mordheim: For buildings, use maps of each level on the same map screen would prob work best. &nbsp;Plus if you go Pro, you could use the teleport Script via the API for characters to move between map sections. &nbsp;(Otherwise, if you use dynamic lighting, as DM you may have to manually move the tokens between levels.) For elevation, there is a thread just below yours that addressed ways to handle that: &nbsp; <a href="https://app.roll20.net/forum/post/5284702/better-w" rel="nofollow">https://app.roll20.net/forum/post/5284702/better-w</a>... Dynamic lighting, a Plus member perk, could probably used to handle cover. Roll20 supports hexes in addition to squares. &nbsp;Yes, you can eliminate a grid altogether. Happy Rolling!
