Adjust mob spawning options

[batuozdemir]

Feature Description

I want to use my void world to make a mob farm, but no mobs are spawning. In an earlier issue the owner told someone to "edit the datapack" for a similar request but I don't know how to do that. Thanks

Hello,
I'd like to see something like this too. To my understanding, if we were to make a datapack to change this, we'd need to add every mob spawn in each category of void.json in biome but that'd be impossible in a large modpack with all kinds of mobs spawning. Ofc to allow hostiles to spawn the light would need to be changed too but that's easily done in a datapack
Thanks in advance,
Jin

I mean yes that adds the vanilla mobs, but if I were to add the other mobs added by other mods it gets complicated, especially if the modpack has 400 mods. I'd have to find all the spawn rates in sources, if available even.

How do other mods with dims handle this, as I am sure that they don't have massive lists like this but still allow spawning?

[Leclowndu93150]

it's done via datagen probably
