How to call my biome registered in forge for custom coding?

Hi there,

I'm trying to call my biome in terrablender for adding custom features, but can't seem to find the registered forge name for my custom biome made in MCreator. I've tried looking in <Modname>ModBiomes.java, but those don't seem to work. 

I did get it working for terrablender's example biomes provided in their github files  and am able to add features there, however, can't seem to correctly call MCreator biome names. Just wondering if anyone knows how to do this.
