so i ve got the scene with absolutelly massive grass areas which i need to populate so i am using pre-scattered patches and nest them inside anothe Forest object, as advised.
Everything works as expected except for the fact that the edge mode doestn work as its supposed to. Its meant to chop off the scatter where the surface ends but instead it making balck ghost artefacts as you can see on the attached render alongside the curbs.
This is very early scene of course but makes me wonder if the edge mode is working properly with nested obejcts.
I will try a spline to chop it off in the next test.
Thanks for any pointers, looking at this issue,
