Came across this thread searching for info on using other types of grids in D&D and thought I would add some info that would hopefully be helpful, seeing as there is already some great info here!
So i have several options available and use a variety of things, some of which are included above so i won't repeat those. But what brought me here was I picked up the Patreon for
Dragon's Rest. Both that and the
Dragon Lock systems are for 3D printing, so having that opens up quite a few options (if you don't have, you can have them printed, but that's not the main point of this thread or the OP's request). MY point here is: Both said 28mm scale for tabletop, but DR's is 1.5" squares, but DL's is 1" squares. So I was like: huh?? (i've always really seen 1" squares or grid...)
What I wanted to share was for running my current game, I also use Realm Works. Luckily, i am running it at my FLGS and am friends with the owner (who is also in the game), and they have a normal drop ceiling. So with about $15 in hardware, a 50' HDMI cable, 2x USB-C extension cables (for power), some Command Outdoor Lighting Clips, and a
Mini Projector (about $300, on clearance still at Best Buy), I'm projecting the maps from the ceiling onto the table itself (instead of from below as one of the previous posts). I can link the hardware if anyone is interested, but it's a pretty simple setup, since the projector can mount to a standard camera mount, so anything that will hold a security camera or GoPro or anything like that will do.
Depending on the sizes and how many different terrains you want, you could request 1.5" squares from
Mats by Mars. I just got a few from them with some different overlays for different games and they are fantastic. Comparable cost to the Megamat you got. The difference mainly is that these would be slightly cheaper (few bucks), have an image or terrain or whatever vs "plain", and 1 sided. Both wet erase and they "feel' about the same. I have a Megamat that has 1" squares/hexes and store them in the same hard tube for transport, so if I need something quick or custom outside of something prepared in Realm Works (which is generally full "maps" with points and all that), I can toss that out on the table and draw some stuff out and throw down some Dwarven Forge (luckily the store backs them as well, so stuff is there and ready to use).
Again, just some more info if people are searching for this type of info. The gridless video is really sweet! I actually want to measure the Star Wars legion movement tools (since we play that in-store too) and see how far that is in terms of grid size. That's exactly how the movement is in that game with the video was saying (place tool next to mini, move mini to opposite side of tool, remove tool).
hope at least some of that is useful!
