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 220.127.116.11
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 18.104.22.168 [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.
Having less than 3 cavern layers appears to cause a rejection mere moments after civilization placement finishes. It provides a seemingly unrelated error message "Placed farming entity without non-orchard crops". There is currently no information regarding this error message anywhere that my search engine could find. Better guidelines should given to avoid this error, though more testing is necessary to determine if it always happens or if perhaps it can be avoided by setting the layer params between the caverns to 0. I spent many hours just figuring out it was the cavern param so, I may not do this myself anytime soon.
Update: Through some testing, and help on discord I've determined the cause. The placed farming entity without non-orchard crops message indicates that a dwarf civ was placed somewhere with inadequate water for underground plants, and that location only has underground trees if any plants (I don't know definitively beyond no regular plants).
I still believe this should be worked into the wiki page.
Other Map Dimension Values May Not Work
Confirmed in .06 (and likely forever.) I made one with 85x85 and I still got 65x65 anyways.
