Somehow, it seems this causes fruit trees to error spam at GetClimate()

Yep :P

Progress! So Octave Scale adjusts rock types vertically and regionSize.. allows for more frequent rock type changes?

ok hang on I figured it out

change ONLY RegionSizeInChunks if you want smaller geological regions (or larger?)

StrataScale seems to directly cause the broken chunks of solid rock when reduced below 16

OctaveScale directly controls vertical strata depth; a setting of 16 will have 16 blocks before rock type is allowed to change; etc

Yeah idk if this one is working right, there always seems to be large hard-edged strips of solid rock on the surface which are super out of place

@matsaa93 Octaves would make sense to me as up/down levels, coming from a musical background, so it probably handles vertcial strata changes

got some resoults with:

 {
 "StrataScaleComment": "Changes TerraGenConfig.rockStrataScale, Vanilla value = 16",
 "StrataScale": 4,
 "OctaveScaleComment": "Changes TerraGenConfig.rockStrataOctaveScale, Vanilla value = 32",
 "OctaveScale": 8,
 "RegionSizeComment": "Region Size in Chunks... Vanilla value = 16",
 "RegionSizeInChunks": 16
}

but with this i get the weird chunks that looks out of place where there is no grass or gravel layer on top

i tried this and got some different resoults that made it have less veriety than last

{
 "StrataScaleComment": "Changes TerraGenConfig.rockStrataScale, Vanilla value = 16",
 "StrataScale": 6,
 "OctaveScaleComment": "Changes TerraGenConfig.rockStrataOctaveScale, Vanilla value = 32",
 "OctaveScale": 12,
 "RegionSizeComment": "Region Size in Chunks... Vanilla value = 16",
 "RegionSizeInChunks": 8
}

and lastly i did this to see if the RegionSizeInChunks had an effect, but it was not a big change it made some changes to what types spawnd but i think it has little effect on the frequency

{
 "StrataScaleComment": "Changes TerraGenConfig.rockStrataScale, Vanilla value = 16",
 "StrataScale": 4,
 "OctaveScaleComment": "Changes TerraGenConfig.rockStrataOctaveScale, Vanilla value = 32",
 "OctaveScale": 8,
 "RegionSizeComment": "Region Size in Chunks... Vanilla value = 16",
 "RegionSizeInChunks": 8
}

but i need to regen the world every time i change this, i also tested it on the same seed and worldgen option.

it seems like StrataScale has most effect on the frequency of change of type.

while OctaveScale is still unknown for me what it does.

i think there is something else that might be the reason for it not changing as ofthen, but i dont know what that can be as of this moment.
