Glitches in displacement map

[ABK]

Hi everyone,

 

I'm looking at creating a generic grass material I can use in 3DS Max and render using mental ray.

 

I've created a grass texture and displacement map and am quite happy with the results. However, a bit of glitching is happening in the render.

 

If you look at the attached images you'll see a 'patchwork' effect on the left hand side and similar on the right.

 

I have used a standard material and the following displacement settings:

edge length: 0.13

Max disp: 10

max subdiv: 16K

 

Any advice from anyone who's encountered the same problems?

You need to subdivide the surface that you are using the grass displacement on. or you could just cut it up a little using the cut tool.
