Can you post a screenshot of what a typical board looks like now? Maybe we'll have some ideas based on what you've got. Is it more of a problem in open terrain or in urban environments? I'm thinking you could use 2d "heightmaps", where lighter colours represent higher elevations. <a href="https://en.wikipedia.org/wiki/Heightmap" rel="nofollow">https://en.wikipedia.org/wiki/Heightmap</a> You could try running on isometric maps with elevation lines, but there could be confusion when units get behind hills. <a href="https://marketplace.roll20.net/browse/set/867/3d-i" rel="nofollow">https://marketplace.roll20.net/browse/set/867/3d-i</a>... If you're handy with graphics software (or willing to learn), you could try making some hexmaps with elevations. <a href="https://www.youtube.com/watch?v=jmPKoL3SnGg" rel="nofollow">https://www.youtube.com/watch?v=jmPKoL3SnGg</a>
