I am trying to add ore veins using Minecraft's built-in datapack functions, and the mod doesn't seem to recognize them even if they're in the right directory implied by the structure of the mod's data.

Does this mod support adding ore veins with datapacks, or only via KubeJS?

That doesn't seem to work. The veins still do not show up.

Yes, send me the datapack you made.

Here you go!

drilling.zip

The files are loose in a global pack loader's resource folder; the full path they're located at is C:\Games\Minecraft\instances\Transylgoonia 2.0 Test\.minecraft\global_packs\required_data\progress_recipes\data\progress_recipes\recipes\drilling

The name field in the json is a text component, so you have to write "name": "{\"text\":\"Lapis Lazuli\"}",
