RTG configuration - Team-RTG/Realistic-Terrain-Generation GitHub Wiki

When you launch Minecraft after installing RTG for the first time, a folder called RTG gets created in your config folder. The RTG folder contains the main configuration file rtg.cfg and another folder called biomes which contains separate config files for each of the biome-adding mods that RTG supports (as well as a config file for vanilla biomes).

Inside RTG’s config files, you’ll find options for tweaking various aspects of your Minecraft world: biomes, caves, dungeons, mineshafts, strongholds, villages, and more. Each option contains a brief description about what the setting does, but if you’re still not sure about a particular setting, feel free to post your questions in the thread.
