This is literally Just Grass! Some simple RnD I did for rendering fields of grass in a relatively cheap and visually pleasing way in Unreal Engine 4.
Here I am using individual mesh strands to represent blades of grass instead of the traditional alpha card approach. I find this to be better when wanting to do large fields, avoiding the often huge overdraw problems of cards. And it turns out using individual strands is a perfect match for Unreals PivotPainter Workflow, making each blade bend and move independently in the wind!
Performance wise, what you see in the video is 0.4-0.5 ms on the GBuffer in 1080p on my regular Geforce1080. Which I think is ok since when you have fields like this your rarely have much else close to render.

This was done in my free time, using my own assets, but for the purpose of using in development of our games at Embark Studios.
