DF2014 Talk:Advanced world generation
I updated the section on Mesh sizes and weighted ranges according to the research I did. I'm not experienced with wiki editing, so feel free to adjust anything as you feel is necessary or offer constructive criticism. --- JoeJoe
FYI [MINERAL_SCARCITY] should be added to the list of options that will affect geography generation. I don't know if this is new in DF2014 or was previously overlooked, but it definitely does affect it. – unsigned comment by 188.8.131.52
Full of meaningless information. What makes a large region large, medium region medium, why would there be three large regions when the default for evil squares in large regions is above 500? Needs to be rewritten from scratch. – unsigned comment by 184.108.40.206 [later editor's note: this comment was left in October 2014. --2128 (talk) 19:54, 12 January 2017 (UTC)]
Cannot find "Desired pre-erosion river count"
"Some prefer to pump up erosion to about 250, and turn the "Desired pre-erosion river count" to 0 for good erosion and no extra canyons." - from the page
After some testing with Volcanism Min/Max, Variances, Mesh, and Minimum Volcanoes, I discovered that the only entry that actually was responsible for generating volcanoes was the Minimum Volcano number. Set at 0, I never spawned any volcanoes during worldgen. Set to any number above zero, and it always spawned exactly that many volcanoes.
Other Map Dimension Values May Not Work
Confirmed in .06 (and likely forever.) I made one with 85x85 and I still got 65x65 anyways.
