About this project
What does Gaia Cores add?
Gaia Cores
Gaia Cores is a mod that generates Gaia Cores underground during world generation.
These cores can generate different vanilla resources, such as ores, trees, liquids, etc - if specific conditions are met.
Different types of cores can be found across the Overworld, Nether, and End - each with their own behavior.
How these cores work, and how to bring them home is not known: players must craft a Gaia Core Scanner and Analyzer to understand how each core operates.
- Generates vanilla resources under certain conditions
- Can be automated
- JEI compatability
- No dependency towards other mods (excl JEI)
- Configurable via gaiacores-common.toml
