⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
This mod adds world layers for ad astra to make ores with GregTech,
trying to do this with KubeJS can cause an issue where Ad-Astra loads before gregtech causing ore issues.
Feel free to PR layers for other mods dimensions if another mod with a race condition is found
