I do love cavern maps and I'm still experimenting. One of the tools I love using can't really handle larger maps, so I'm playing around with some other techniques and trying to solidify the ones I do like.
Practice makes perfect......or in my case "good enough".
Of course I started with the large map that goes out to my Patrons, but then I take that map and shrink it for free release on my Patreon page, but this time I've also uploaded a "larger" copy specifically for VTT use. I realize the file is big for actual VTT use, but I assume folks will cut it up into sections so they can just use the smaller chunks.
Just click on the appropriate picture to get to the file you'd like....
