Mowed Grass in Blender 3D

This is grass that has been laid out to look freshly mowed or cut with a lawn mower. I achieve this by using four particle systems on a cube and duplicating this cube as many times as needed to fill the scene (or using an array modifier). There are no textures needed to achieve this result, and renders look very good at low sample settings. Use a HDR in the world settings to get even better looking renders.
