Multiple Biomes Not Generating in Custom Dimension (MCreator 2024.4)

Hi guys,

I’m working on a custom dimension in MCreator 2024.4 that generates similarly to the End (floating islands). I’ve added multiple biomes to the dimension’s biome list, but only the first one seems to generate in-game - no matter what I do, the other biomes never appear.

I’ve already tried adjusting parameters like noise size and enabling/disabling certain biome settings, but nothing changes. It seems like only the first biome added is being used for world generation.

I know that changing the world type to something like "Nether-like" or "Overworld-like" might help, but I specifically want to keep the End-like floating islands generation.

Has anyone encountered this issue before? Is there a way to get multiple biomes to properly generate in an End-like dimension without switching to a different world generation type?

Thanks in advance for any help

You need to make sure ranges of biome properties really vary and don't overlap.

when using The End world generator, biomes generate starting from the center of each island, and ring out depending how many biomes youre adding. biomes that generate closer to the center of each island will use a weight around 1-0, and as they ring out, they get closer and closer to -1. ill show what i did for a recent mod i made, hopefully its of help

Erosion is the only option that matters as The End world gen type only uses Erosion
