Not find a really answhere on internet. Can you change a biomem wheater inworld ? In other words, exampl: can you change a desert in a forrest with rain ? or is minecraft not smart enough for that ?
You cannot change a biome in Vanilla minecraft, if you wish to change your Empire residence biome you can simply message the Senior Staff/Community Managers to request you res to change biomes and the cost will be deducted from your rupee account.
Senior Staff can change the biome on your residence in Town. Details are here: http://empireminecraft.com/wiki/senior-staff-services/ You currently cannot do anything about the weather though.
