You’ve got a lot of work ahead of you my man!
Here’s the work you’ll need to do for colors:
Then you can get started on the harder stuff. Make some prefabs (easy enough), assign constraint types to them and you’re ready to go! Time to make sure you get the density and threshold noises to within about .001 of the value you want. Repeat for each prefab (this is trees, rocks, etc.).
Once those are all nice and set for one biome you gotta get to the cave system by perfecting some 3D noise. Simple enough. But since this is for a sovereign world you gotta make sure you don’t make it too OP with 0 guidelines.
Then tackle some strata. This is about 1/80th of the work needed for a “good” strata if you really want to control every aspect.
After that you get into heightmaps. They look easy but if you’re trying to control every variation of noise within the practically countless variations of possible seeds so that you can control every aspect of your world then more power to you!
Repeat the above per biome.
I’m excited to see how it looks!
I will say I agree and always have agreed on roadmap and needing more details.
