Make your own map from heightmap and painting!
Biome Uniter lets you turn a heightmap and drawings into a custom Hytale world, with different biomes placed wherever you want on the map.
Only one command you need:
/BIOMEUNITER This command is going to trigger a Biome Uniter window to open.
Quick tutorial:
Step 1: Type in "/BIOMEUNITER" (Make sure you have OP powers)
Step 2: Pick heightmap or empty square.

Step 3: Adjust heightmap and add corresponding biomes. (You can skip this step if you have empty square, just make sure to adjust border and square biomes!)

Step 4: Paint any amount of biomes you want on top of the heightmap!

Step 5: Generate and name your new world. You will be transported to the center of the map, you can now enjoy your generated world! Switch worlds using "/tp world X"

Alerts: They are important information you need to know before you make a map. Most of them are in gallery now. (will also show up during using a mod)
Hope the mod will help you get your vision out to the people! Can't wait to see your creations!
