There are a few things I'm having trouble with: First, something is causing a crash when you try to create a new world, it crashes with:

 

[17:12:29] [server thread/INFO] [FML]: Loading dimension 0 (New World) (net.minecraft.server.integrated.IntegratedServer@6149c883)

Which is the return in this function:

@Override
public IChunkProvider createChunkGenerator()
{
   return new AAChunkProvider(worldObj, worldObj.getSeed(), false);
}

 

Main

WorldProvider

ChunkProvider

 

There are other issues but I want to see how fixing this affects them first.

You never assign anything to worldObj.

I tried this before and got a crash on loading too:

I did:

public AAWorldProvider()
{
this.dimensionId = Reference.DIMID;
this.hasNoSky = false;
this.isHellWorld = false;
this.worldObj = MinecraftServer.getServer().getEntityWorld();
}

Ok...that was caused by setting canRespawnHere to true, but that still doesn't allow the world to load:

I rewrote everything but the biomes, now it loads and I can get into the dimension, but I'm still having a few issues.  Most importantly, only one biome is generating, when I added 2 to my WorldChunkManager.  I still have to add other things back in one at a time, so that's the only question for now.

 

 

WorldChunkManager

This is odd, it IS spawning both, but the biome indicator on F3 never says anything but plains.

 

 

Nevermind, fixed it.  Now, the other issue I've been having is removing the vanilla generation.  I overrode  ChunkProviderGenerate#populate in my class that extends ChunkProviderGenerate and implements IChunkProvider, and changed it to:

 

 

@Override
public void populate(IChunkProvider chunkProvider, int x, int z)
{
BlockFalling.fallInstantly = true;
int k = x * 16;
int l = z * 16;
BiomeGenBase biomegenbase = this.worldObj.getBiomeGenForCoords(k + 16, l + 16);
this.rand.setSeed(this.worldObj.getSeed());
long i1 = this.rand.nextLong() / 2L * 2L + 1L;
long j1 = this.rand.nextLong() / 2L * 2L + 1L;
this.rand.setSeed((long)x * i1 + (long)z * j1 ^ this.worldObj.getSeed());
MinecraftForge.EVENT_BUS.post(new PopulateChunkEvent.Pre(chunkProvider, worldObj, rand, x, z, false));
biomegenbase.decorate(this.worldObj, this.rand, k, l);
MinecraftForge.EVENT_BUS.post(new PopulateChunkEvent.Post(chunkProvider, worldObj, rand, x, z, false));
BlockFalling.fallInstantly = false;
}

 

 

And of course specified it in my custom WorldType, but all the features omitted still generate.

Still can't figure this one out.
