This mod alters vanilla rock strata worldgen to allow more varied (and more numerous) rock layers to generate. In vanilla worldgen, some rock types dominate and prevent others from spawning because they have precedence during generation. This mod allocates a piece of the column to each rock type that is queued for generation in a given area, rather than allowing a few to fill up the column before the others get a chance.

This mod should increase the likelihood of rarer rock types like limestone or chalk generating, and will especially improve the distribution of modded rock types appended to the end of the rock strata variants list (and therefore at the end of the line to generate).

This mod should be compatible with mods that add new rock types, ores, etc. It will be incompatible with any mod that specifically alters the GenRockStrata.genBlockColumn method, as that method is changed and overwritten by this mod.

This mod is best used with new worlds, but shouldn't cause any issues when installed mid playthrough (back up first!), except that newly generated chunks may have some abrupt layer transitions. It doesn't affect terrain shape or modify the heightmap in any way, so you shouldn't get any ugly cliff chunk boundaries. You may regenerate old chunks to repopulate rock types with /wgen regen [radius around you in chunks]. Take care, as this will delete anything you've built in the area! Back up your save before trying it.

Note: This mod does not make specific rock groups (e.g. sedimentary, metamorphic) more common, or adjust the likelihood for any rock type to be able to generate. It isn't a targeted buff to limestone or bauxite spawn rates. Rather, they will show up where they should have been all along.

is this compatible with v1.19.8?

💬 AzuliBluespots, Sep 18th at 8:56 PM

Something seems to have changed enough in terrain generation in 1.20 pre1 that this, just like rivers, ain't generating terrain at all :c

Hello, great to see someone tackling the rock stratta issue in game.Could yopu perhaps fix the phyllite generation that is currently bugged? It should not be generating just couple blocks above mantle under ingeous layer but more like slate and marble generates. Phyllite is a metamorphic rock so just like slate and marble. Thanks.

Maestro_ Nope, this mod doesn't affect the worldgen heightmap or interact with landforms in any way so it shouldn't cause weird chunk borders. Worst that might happen is some abrupt rock strata transitions, but that will only be super obvious in cross-section (like on a cliff or something)

Will this generate mismatching chunks if I try to use this in an existing world? (Like a mountain range cut in half by the new generation)

💬 chispsAuthor, May 27th at 5:23 PM

Xozkov yes, this is fully compatible with landform mods! I personally use it with Plains & Valleys.

💬 Xozkov, May 27th at 2:15 PM

So with this only affecting rock strata worldgen, would that make it compatible with terrain worldgen mods such as VanillaPlus or Plains & Valleys/Fields & Plateaus or no?

good mod

💬 chispsAuthor, May 16th at 2:32 PM

MadGnome thanks for the report, that's a new one to me. I'll take a look. Are you using any other mods that affect worldgen?

Trying this out on a 1.19.7 server, getting a lot of console spam with this error message.

Hopefully this fix can go into 1.20 - it is needed!

💬 chispsAuthor, May 2nd at 5:49 AM

phol thank you! I'm glad people are enjoying it!
