Description
Install TFCGyres-RockLayerSize, and your trips will be 50% shorter, or your money back!
This is a lowcode mod/datapack to decrease the rock layer sizes by a factor of 2 for the TerraFirmaCraft overworld.
Concept originally from Per Fabrica Ad Astra's TFC patch in 1.7.10. TFC 1.12 and 1.18 have this change as an option, so this mod makes this change in an easy to apply fashion for 1.18.
This is recommended for single player (SSP) mode and for anyone else who wants lower exploration requirements.
Implements the datapack rock_layer_settings option as shown here: https://terrafirmacraft.github.io/Documentation/1.18.x/worldgen/dimension/#rock-layer-settings
Adding this mod to an existing world will result in chunk boundary artifacts in rock layer types, but will be otherwise undetectable.
Just think, your rock types could look like this (thanks to BlazeMap and Cartography!)
