Biomes
Biomes let areas of your world use their own weather. Use On Enter COZY Biome and On Exit COZY Biome to run instructions when the COZY track point moves between them. The track point is usually the camera or the player. Use Is In COZY Biome to check whether the track point is inside a biome.
Use Set COZY Biome Weight and COZY Biome Weight to control and read how strongly a biome is blended in.
