You will find the Main-Configuration at plugins/RealisticWorldGenerator/config.yml
The Main-Configuration should look near the same like this:
In the Main-Configuration you'll find important Configurations, that will affect all RWG-Worlds.
This is your License-Key, if you'll be asked by an Supporter for this key, just give it to him. Only this license-key can be used to deblock your license, if your license has been blocked. You're not able to change this Key by editing the config!
This Option can be set to true or false. If you set this to true some fences will spawn in the tinier trees to make them more realistic.
This Option can be set to true or false. If you set this to true, every world will have it's own configuration-files to make different looking worlds on one server with RWG.
This list contains all Worlds, that uses PerWorld-Configs. All not included worlds will fall-back to the configs from the main-folder.
This Option can be set to true or false. If you set this to true, all ores will spawn in vines, that means, that they stick together like a tiny worm. If this option is set to false, every ore will spawn at 1 block, there will be no connected ore-structures.
This Option can be set to true or false. If you set this to false, the old Biomes-Design will be used. The biomes wouldn't be able to get fully customized. It is not recommended to set this to false
This Option can be set to true or false. If you set this to true, newly grown sepplings in RWG-Worlds, that are using per-world-config will grew as RWG-Trees. So the plugin replaces the default Minecraft-Trees
