You mean it doesn't have the obsidian layer?

Make sure you're actually in the biome. You probably wont spawn in it, you'll have to go and find it.

An easy way to help you find it is to add this to the bottom of your @Init:

 

 

GameRegistry.removeBiome(BiomeGenBase.ocean);[/spoiler]

 

That will remove the "ocean" biome. Repeat for all the vanilla biomes, then you should spawn in it.

is there a way i can add this to my custom dimension

Quite simple.

 

Put this in The WorldProvider:

 

public void registerWorldChunkManager()

      {

            this.worldChunkMgr = new WorldChunkManagerHell(Base.yourBiome, 0.8F, 0.1F);

            this.dimensionId = Dimension.yourID;

      }

 

Dimension.yourId is your Dimension ID.

Base.yourBiome refers to your Biome that is loaded in the base mod class.
