Lest you think I forgot about this hex map project... I haven't. I got side-tracked last week with new PBE Games releases, and then sports-related events. Now it's back to the hex map, and a refinement pass on the previously generated big hexes.
Next I repeated the random edge terrain assignment process to all the interior terrain hexes that contained mixed terrain. I specifically didn't randomize these further because I still have to do terrain generation for the small hexes. I don't mind messing with the coastline, but I want to see how the generator deals with using overlay hex terrain for generation, so fixing split hexes is enough for now. Here's the final result after all this was complete.
