Grass rendering completely wrong

[lapinobel]

Whenever I try to render a scene which has grass (downloaded from the skindigo material library), I get this weird rendering with planes in all directions. When I replace the texture with a 'normal' texture, it works fine. Looking for a way to render a decent grass plane.

look slike there is some massive displacement on the material and your grass area needs massive subdivision to work.
For grass use scattered patches of grass it works way better in all possible way
