Grass Displacement Problem

[devilreborn]

I've been trying to use Vray to render a Sketchup model, which is part of my school project. The problem is, when rendering grass in front of the building, it is common sense that displacement will be used especially there are a few scenes where the grass is close to the camera. However, I can't find an appropriate displacement map to make it look realistic - using the original texture as a displacement map make the grass look like green spikes. Can anybody suggest where I can find such a map to make realistic grass? Thanks!

Displacement doesnt usually look realistic for grass simply because blades of grass are not straight or spikey looking. Your best bet is to add the grass in post-process. Nomer has a great link to a tutorial on how to achieve this if you look around the forum (I can't remember the link right now )
