# Possible biome modes:
# Normal - use all features
# FromImage - get biomes from image file
# Default - use default Notch biome generator
# For old maps two more modes are available:
# BeforeGroups - Minecraft 1.0 - 1.6.4 biome generator, only supports the biome groups NormalBiomes and IceBiomes
# OldGenerator - Minecraft Beta 1.7.3 biome generator
part I change Normal for the biome mode to "FromImage" delete the region folder and then start my server up. It re makes the world and changes the FromImage I typed back to Normal!
