Jeez, I hope I'm not necro'ing this too bad...
I am literally unable to create flux in any world that I create using the perfect world creator, despite whatever settings I use.
I've even gone as far as setting "Percent Below Igneous Extrusive Threshold" to 97%, but I can't get more than a speck of the map to produce flux stone. (Yes, I've used the site finder).
Am I doing something wrong? I've searched the thread, but aside from the volcano "how-to" I can't find anything that really relates to this problem. If someone could explain what to do, I'd be eternally grateful.
EDIT: Okay, yeah, never mind, fuck me. I set mineral scarcity to 195 instead of 1950; when you have it set really low, flux becomes nearly non-existent on the map. That was why I couldn't find any flux. Disregard this post, sorry for the necro.
