i just downloaded blender , made a model for the grass , played with the material a bit, and got to this point
currently i do want to add 2 things , color variation based on a noise texture , and a scrolling noise texture to make the grass planes bend like wind , i currently do not know how that is done
additionally to that i would like any other tips that you might have that can range from improving the 3model to modifying the material to trying a different approach that i might not know or thought of
meanwhile , i will look into what shader materials are
