About this project
What does TerrablEndFix add?
TerrablEndFix
(it's pronounced "terrible end fix")
There is a bug in TerraBlender 1.21.1 that prevents the vanilla Small End Islands biome from generating at all. This was fixed for 1.21.5+ but not for 1.21.1. This mod simply fixes the issue in 1.21.1, since TerraBlender is no longer maintained for that version.
I could not reproduce this issue in the Fabric version of TerraBlender, but a Fabric version is provided just in case you run into it somehow.
This mod is very simple, it changes one variable. Unfortunately for this to work, TerraBlender's endEdgeBiomeSize and endIslandBiomeSize config options need to be different (which they are by default). You can tell it worked if you see Edge biomes detected where island biomes should be, fixing... in your log (and of course, Small End Islands generate again)
