When I apply the grass as foliage to more angled landscape areas, some part of it looks like flying in the air. Is there any automated solution for that problem?
You should probably make the mesh smaller, since there isn’t an aligning system which sorta bends the model. Try making individual pieces for those kind of areas, and your big pieces for the flatter surfaces.
Yes, making the mesh smaller was the solution for me. Though it has been a year, maybe this answer can help some others
I was having these issue, I restart the engine and it works fine.
