Retrogeneration of Galacticraft ores on a custom map in forge 1.12.2 server.

[cosmocaos]

Hi, I'm triying to do retrogeneration for galacticraft ores in a 1.12.2 forge server, with a custom map (Minecraft version 1.9, Apterra is the name of the map, downloaded from planetminecraft). I tried with two mods, CoFH and ChunkPregenerator.

I have no success with CoFH World, tried turning on and off the options for retrogen in config/galacticraft/core.conf and in config/cofh/world/config.cfg.
I have used the example of galacticraft.json found here in the forums and updated the ore names of galacticraft 1.12.2.

With ChukPregenerator, I only retrogenerated Aluminium and Oil. I did turn on overworld ores on config/Galactigraft/core.conf. And used activeworldgenerators=micdoodle8.mods.galacticraft.core.world.gen.OverworldGenerator for ChunkPregenerator.

I have searched in google, discord, reddit, and I'm clueless, there is a lack of step by step tutorials for doing retrogeneration on custom maps, don't know why.

I would appreciate any help on the topic.

This is my galacticraft.json file:
