Problem with grass

[lalakis]

Hi
I have a problem with a grass material when I apply it on a surface that I made from contours in sketch up (so there is some hidden geometry there)
I used the material "Architectural green grass"
When I render the image I get some strange lines on the surface of the grass where the hidden lines of the mesh are.



Any suggestions?

I've thought that it might be some shadow created from the difference in the plane but it's not. I unchecked both cast shadows and receive shadows at that area but still the same result.
Any ideas?

Re: Problem with grass

I am sure I had this problem before but we resolved it, have a search of the forums. I'm sorry but off the top of my head I just cant remember the solution.
In fact as I type this I think we may have shown hidden edges in the model, then selected all the faces and apply a smooth. Try that.
