Ok, thiss has been an ordeal.
height map taken from Tangram heightmapper using Tallmanbrads tutorial on his youtube channel.
its a 10K map
i had to go in with GIMP and smudge some areas of the height map so cities would build at all. original had too much variations in height to let a city spawn.
I noter there are a high concentration of pois creating town like areas will remain to be explored if they make sense in game. They are linked with paths/roads. check the top right of the map, it spawned 7 ship poi's .
Overall the final render with errosion rivers and roads took approx 3 hours on a Ryzen 5800X . It is the roads that take all the time. watching on perofmance monitor the road making only uses 1 core. interestingly it moves cores but only ever uses 1 core at 100% for a while then switches to another core. Shows 8% CPU usage. Maybe the road generation cant use multi threads?
