Hello! I created a biome today, and when i went into the game this is what i saw:

 

 

Here is my Biome gen code :

 

 

 package mod.gmod622.biome;
import java.util.List;
import cpw.mods.fml.relauncher.Side;
import cpw.mods.fml.relauncher.SideOnly;
import mod.gmod622.main.mod_ZeCraft;
import net.minecraft.block.Block;
import net.minecraft.block.material.Material;
import net.minecraft.world.IBlockAccess;
import net.minecraft.world.biome.BiomeGenBase;
import net.minecraft.world.gen.feature.WorldGenerator;

public class BiomeGenZecraft extends BiomeGenBase
{
private WorldGenerator UnDeadworldGeneratorBigTree;
public final Material blockMaterial;
public BiomeGenZecraft(int par1)
{
super(par1);
this.blockMaterial = Material.water;
this.minHeight = 0.1F;
this.maxHeight = 0.6F;
this.spawnableMonsterList.clear();
this.spawnableCreatureList.clear();
this.topBlock = ((byte)mod_ZeCraft.ZeGrass.blockID);
this.fillerBlock = ((byte)mod_ZeCraft.ZeDirt.blockID);
this.setBiomeName("ZeBiome");

/** this changes the water colour, its set to red now but ggole the java colours **/
this.waterColorMultiplier = 0xE42D17;
}
}

if you need anything else just tell me

You are casting your block id to a byte. It needs to be in the byte range to keep its value.

Terrain block id must be lower than 256.
