Hello,
this is a Dream ... a kind of vegetation Editor (to be honest, like the CryEngine5 uses).
I am sure, it is hard to crate.
Features are, that You can greate groups of different plants, assign f.e. a random size, how much space is between the different plants, a random rotation and how they bend in the wind, etc.
With one click, then filling the whole terrain with the vegetation group.
What do You think about this idea.
Regards,
R.E.Z.
