Structures

Structures with a checkbox are self-explanatory.

Generate village of type: The word in the list is the type of the village to spawn. Keep "none" to remove the village spawning.

Generate ocean ruins in this biome?:

  • NONE: No ocean ruins
  • COLD: Ocean ruins made of stone
  • WARM: Ocean ruins made of sandstone

Entity Spawning

A spawn entry is equal to an entity

Entity: The entity to spawn. Put only mobs, otherwise, the game will crash.

Spawn type: This parameter controls the spawning type for the biomes where his mob is defined to spawn in.

  • A mob marked as Monster will only spawn in the dark or at night.
  • A mob marked as Creature will spawn under direct sunlight on grass material blocks only. Do not use this spawn type with mob type living entities as they will not spawn
  • A mob marked as Ambient will spawn under any conditions except if block type prevents it, but this category should be used for mobs with no gameplay effect such as bats
  • WaterCreature will spawn in water, but with no other limitations

Spawn weight: This parameter controls the priority that the mob has over others when the game is choosing what mob to spawn. A higher weight means more mob spawns in the game will create this mob. Make this lower for animals, compared to monsters.

Min and max group size: The minimum and maximum set here set the size of groups that the mob will spawn in. Be warned that mobs that try to spawn in groups of over 20 will struggle to do so (mobs will rarely spawn).

Biome Generation

Generate biome in overworld: Can your biome be in the overworld?Is your biome can be in the overworld?

Biome weight: This parameter controls how many times your biome will spawn on 1024 of the same biome type (ICY, COLD, WARM and DESERT).

Biome category: The type of biome

Biome parent: Your biome will always spawn near to the biome selected (it will be used for biome borders and transitions).

Example: Deep ocean always spawns near the ocean biome.

Biome dictionary types: Biome types to help some mods to do the generation.

Biome base height: This parameter controls the height at which the biome is. Mountains have this parameter set to a big value for example.

Biome height variation: The height variation of the terrain. Higher is like a mountain, a lower value represents a flat plain and 0 is like an ocean
