Do these maps work with Roll20/XXX virtual tabletop?
You can import the JPG files into any system you use to play your games online, however, if you want to use the .mod file you will need to use Fantasy Grounds Unity and to use the .fvttadv file you with need Foundry VTT.
How do I use the .mod File?
Don’t you make Foundry VTT files?
Yes, many of my new maps have Foundry VTT support, however DMsGuild won’t allow them to be sold via their site which only supports Fantasy Grounds. To get the .fvttadv files you’ll need to be a Patron, sorry.
I like your maps!
Not really a question but… you can support me on my Patreon (Patreon.com/angelamaps) and get a large library of maps (including this one) and new maps every month.
