Thanks for the input. I tried adjusting the perpendicular setting (I set it to 100%) and it did smooth out some of the grassy areas, but the big choppy section stays the same.

If I manually populate it, I can render the grass, but the scene crashes when I turn on the other layers of the ecosystem.

I think I'll try painting the grass in next. This is very frustrating. :)

Thanks again for taking the time to help.
