I'm trying to troubleshoot or prevent cave spawning in the ancient 1.7.10 version. Modpack is locked at 1.7.10 because that's what Gregtech supports.

I know it's ancient code and I don't expect a fix. However if I could browse the code here or directly to see how I could disable cave spawning that'd help.

Essentially mobs spawn indoors ignoring light level just off the ground, and also rain from the sky over the ocean and land.

Verbose debug logs show spawnNewMobCaves events constantly, even with the following settings:

minecraft@odin3:~/servers/SadZombieLand/config/ZombieAwareness$ grep -i cave * Features.cfg: # Spawn extra zombies in caves where other zombies already are if dark and away from player until Spawning.extraSpawningMaxCount is reached Features.cfg: B:extraSpawningCave=false Spawning.cfg: I:extraSpawningCavesDistMax=256 Spawning.cfg: I:extraSpawningCavesDistMin=255 Spawning.cfg: # The max count of zombies active in loaded chunks for extra cave spawning Spawning.cfg: I:extraSpawningCavesMaxCount=0 Spawning.cfg: # Max amount of zombies that can spawn together in a cave Spawning.cfg: I:extraSpawningCavesMaxGroupSize=0 Spawning.cfg: B:extraSpawningCavesOnlyOnStone=true Spawning.cfg: I:extraSpawningCavesRandomPool=0 Spawning.cfg: # How intensively it tries to spawn mobs in caves Spawning.cfg: I:extraSpawningCavesTryCount=0
