Floodgate/GeyserMC

Download: here

Floodgate and GeyserMC allow Minecraft Bedrock players to join your Java Edition server. Bedrock clients do not support custom biomes and RealisticSeasons hooks into Floodgate to detect which players are Bedrock. Bedrock players will see the following vanilla biomes instead of the custom biome colours:

Season	Biome
Summer, Spring	Default biomes
Autumn/Fall	minecraft:savanna
Winter	minecraft:frozen_river
