I ended up getting Other World Mapper, and might use some of them in that, though if you still decided to do the Hex Kit usable ones that would be cool (as honestly I find Hex Kit so much easier to use than OWM).
Question: Is it ok to remove the outline for the hexes in the transparent files? Since Other World has hexes, it shows both on the map. Some of your tiles fill a gap the ones that come with the basic version of OWM doesn't have, and I really want to use them. Also, what is the correct name to use for giving credit?
