Hello friends.I am just testing that how can we create cool grass effect using vray displacement modifier.I found many tutorial on Internet for this effect and I just added a few more steps to make is more natural.
Firstly I created a simple plane 33 segments the applied some noise to make it like an uneven surface and also applied turbosmooth and then an UVW Map modifier which is very essential without this displacement won't work and finally applied vray displacement modifier.All the setting are shown is the image.
I used two grass texture one for green and another for dead grass in a Blend metarial.I used noise in the mask.
Finally I rendered it with vray sun.One more important thing is the you should use Adaptive DMC method insted of Adaptive Subdivision because DMC will give you fine details of the grass.
And then I did some color correction in photshop.
