Hello,Guys：

> 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. 😭  
If you know, please tell me.Thank you! ❤

Good luck!
