Yes, it's a bird's-eye view, so lots of grass! I usually use lower camera angles so the populations are much smaller.
Thanks for the suggestions for using different grass objects depending on the distance. Sort of like a manual LOD, but not too hard to set up.
After my last post I realized there is an obvious flaw in my suggestion to add a camera selection list to the population panel: If you switch cameras you would have to manually update the selection for each population. This might be done fairly quickly in the node window by dragging out new connection lines, but still. It's probably best to leave it as-is, using the current camera.
This is what happens when I post suggestions before my second cup of coffee.
