[Algorithm] How to generate random grass on field


I have a question,How to generate random grassland on field like this picture?

I used Berlin noise, but it don’t work well, there are many separate points. I hope to generate a more natural grassland like this picture.

I couldn’t find a function in the source code. :sob:
If you know, please tell me.Thank you! :heart:

Good luck!

Try to create a new mapgen with its overmap id set to field.
