Yeah, would have used hexes if I had taken the time to find some sort of hex making tool. As it was, I was just following the tutorial and adapting. As you can see in the posted update, I have gotten rid of the "grid" altogether. Wasn't doing it for me. I like the Solid Noise Overlay that added a "mottled" look. Even had a side effect of making the water look even better.
Honestly, this map turned out way better than I expected. The doors were a PitA and I am still not 100% into liking them. Better than the first attempt though.
For the moment, I am going to continue using this particular technique to finish up a series of "portions" to a larger dungeon. Been playing around at running a short diversion from the Gemini game. Felt really like going "old school" with dungeons and all that.
And then I am going to attack that Regional map project.
For this version, I remade the doors and moved the Doors layer up above the Drop Shadow. I turned down the Drop Shadow layer opacity to 70% from 80%. I messed with the water technique described by torstan and I am not sure if I like it better or not. Any lower opacity and it looks like a discolored blob.
Next step is to post a key and write-up for this section.
