I've been trying to figure out biome spawning in Forge 1.7.2, but can't seem to get them to work.  I've got this instance in the base class:

 

public static BiomeGenBase exampleBiome = new BiomeGenExample();

 

And then I have the constructor set up in BiomeGenExample:

 

public class BiomeGenExample extends BiomeGenBase {

public BiomeGenExample() {
	super(50);
	this.biomeName = "Example";
	this.topBlock = Blocks.bedrock;
	this.fillerBlock = Blocks.dirt;
	this.rainfall = 0.5F;
	this.temperature = 0.5F;
                this.minHeight = 0.2F;
                this.maxHeight = 0.5F;
	this.enableRain = false;
}

}

 

I know previously there was a method in GameRegistry to make the biome spawn that is no longer there.  Should I have anything else to make this biome spawn, or am I just not looking hard enough?

Thanks for the workaround!  It seems to be generating now.
