Experimental grass

I have tried to reproduce a grass texture (first time I've done it!). Quite happy with the result, I still have a lot of trouble with the roughness, and the heigh (is it really necessary, apart from rendering?)

Texture inspired by this reference :

I'm aware that the renderings are very bumpy, but it's my wish to emphasize the "fluffy" side
