Hi! I'm trying to reduce the spacing between the veins because the default is too much, but the example on the readme doesn't work in 1.21.1.
Could someone help me?

If I understand well, the default spacing is 1024 blocks, right? i would like to reduce to idk 512 maybe

Thank you!

KubeJS support isn't in the 1.21 version yet.
You can copy the jsons out of the mod and create a datapack:
