Here is what I think is a good render of my terrain with flowers. I used the paint shader for density on all of my objects, adjusting the placement of a, b so they would not trip over each other. I have several surface shaders on the terrain with altitude constraints. Where I have traveled, picture perfect green only exists in manicured lawns. That is okay for home, but nature is usually a little different. I also used low poly trees in the distance as I was not doing an animation with closeups. The green vegetation around the flowers is the 3 leaf clover patch. Thanks! I know it needs dandelions, bees, and birds.....but I had to settle for three objects. Second image has a vignette applied. Works for me.
