This took quite some time! The tiles are basically Hirst Arts tiles. To speed things up a bit, I created a few more molds from the pieces I cast. The new molds did, as expected, shrink about 1 mm, so things don't exactly fit together. As this is going to be a 2.5D dungeon, that won't matter much. The few walls I'll add will go on the plates, to create more complex bigger rooms.
I'm working on a few more center pieces (stairs, wells, ritual rooms). I'm creating these mostly from foam core, just as the octagonal room. The doors will be based on a master I'm sculpting from Apoxie, mold it, and then cast in dental plaster.
As I ran out of spray coat, I resorted to some brush-on clear coat, which unfortunately left a white film in some places. Should have used white glue instead.
