New terrain types and features

[dunkleosteus]

I'm looking to add new types of terrain (ie where grassland, grassland hills, plains, etc are terrain types), new features (where natural wonders, forests, jungles etc. are features) and hopefully, allow them to spawn without requiring custom map scripts, just by forcibly modifying how the existing scripts run. Where do I start? I've been looking around for help, but I can't seem to find any information on altering generation.

Terrain and features types are hardcoded in the game's map utility script, so if you don't want to use custom mapscript, you'll have to replace at least one of those files in your mod, making it incompatible with other mods replacing the same file.

for YnAMP I use AssignStartingPlots.lua because you can override the functions from the other map utility scripts in it as it's the last file included in the mapscripts, and I needed to edit it for TSL anyway.

And so, where to start would be ..\Steam\steamapps\common\Sid Meier's Civilization VI\Base\Assets\Maps\Utility
