When generating a world in 1.19.2 (mod version 4.6.1) I'm not seeing a config file to tweak/disable orespawn in either the main config folder or the world's serverconfig. I seem to recall more recent versions having the config in the serverconfig folder of a generated world. Is this bugged or am I overlooking something?

I'm using forge 43.2.4 and removed all other mods to test this.

Since ore generation now uses the vanilla "Features" registry, it is no longer configurable in the mod's config files. Instead, you can use a vanilla Datapack to edit it, same as if you wanted to disable iron ore from spawning in a world.

The base files are here: https://github.com/legobmw99/Allomancy/tree/main/src/main/resources/data/allomancy/worldgen

Here's an example of disabling vanilla worldgen with a datapack: https://www.planetminecraft.com/data-pack/minecraft-but-without-ores/

ah, that helps clear things up. I appreciate you clarifying and providing some resources. I'll take a look and try figuring it out. Thank you!
