Custom mobs not spawning in custom dimension/biome
Wed, 01/22/2025 - 14:16 (edited)

I made a custom mob, a animated entity to be more specific i made it with geckolib and the mob works ive tested it with the spawn egg but its just the in the custom dimension/biome it dosent spawn. I went to spawning section of the mob and i did specify where it should spawn and i gave it a spawn weight of 100 and made the mob type a creature so it should spawn more. can anybody help me? also sorry if this is confusing im not good at explaining things.

If it uses creature spawning…

If it uses creature spawning type, there is an additional tag that you need to put your custom biome's top block in to allow creatures to spawn on it. Specifically, you will need to put the block that is at the top of your custom biome in the minecraft:animals_spawnable_on block tag. It also might be a good idea to put it in the minecraft:dirt block tag to allow plants to grow on it better.
