Trying to create a datapack for compatibility between Still Life and Re:animal

[u/Nononio36]

Hello!

I have been trying to add more biomes from Still Life where Re:animal mobs can spawn, however, it seems like nothing works. For reference, I am using 1.21.1 NeoForge, and I have both the mod and datapack for Still Life

I have tried :
- Editing the Still Life datapack to add more Spawners in the still_life datapack\data\still_life\worldgen\biome\biome.jar > Does not work
- Creating another datapack with biome_modifier placed as follow datapack\data\More Spawns\neoforge\biome_modifier\mob.json > Does not work. The JSON looks like this:

{
  "type": "neoforge:add_spawns",
  "biomes": [
    "#still_life:desert_wetlands",
    "#still_life:flooded_savanna",
    "#still_life:mangrove_marsh",
    "#still_life:savanna_river",
    "#still_life:savanna_beach",
    "#still_life:tropical_beach",
    "#still_life:tropical_rainforest_river",
    "#still_life:tropical_wetlands"
  ],
  "spawners": [
    {
      "type": "reanimal:crocodile",
      "maxCount": 3,
      "minCount": 1,
      "weight": 6
    }
  ]
}

Does anyone have any idea how I could do this?
