Um.. could you tell me how do you render the grass? From game dev perspective, what technique are you using, is it a procedurally copy+paste model or is it just a math function (like shader) or maybe something else? Also what game engine are you using? I guess UE4?
I only knew how to do it with model but that seems like a ton of mesh... it should kill performance on any PC but your video is very smooth.. so I guess it's some other technique? But I have no idea how to do it.
This is kind of style I had in my head for a while but I never could get it done. I would really appreciate your response. In any case I hope you don't mind me copying it, I doubt I will publish it anyway...
