Nurbs plane scale displacement problem ?
 

Hi everybody

I have a scene where I have a nurbs plane displaced by on ocean shader with a dielectric material assigned to it.

Now everything is fine when i render, no problem there.
I want to scale up my nurbs plane to make it bigger, BUT when I do my displacement dissapears, it goes completely flat which isnt good.

below is my displacement which is how i like it. The plane is 50x50x50, I want it to be 800x800x800 (goes flat at this scale)

So can anybody tell me how to sort this out without losing my displacement on my nurbs plane ?

If so that would be great.

Thanks
