Thanks andybot, I understood the opposite, damn google translator and cursed me that I do not know English, retry the test tonight, thanks again.

As soon as I can post it thanks BHB

Thanks for the answers
For Bhbarchitects, no it is part of a group (I had already read of problems with the groups).
For Mitcorb, the water level is placed above the infinite plane of SU.
I'm going crazy for this thing.

Good morning everyone, first of all I apologize for my English, I have a problem with vray displacement, the material can be seen in the preview correctly, but when applied displacement disappears remains completely flat.
I tried doing a simple test in a vacuum of SU drawing I drew a face, I applied the material, started without setting the render lighting, background and the image is correct (test 1) then I added a simple object I started render the displacement but disappeared and the texture is connected (test 2).
I have tried using different materials with different textures, but the result is always the same.
Why does this happen?
Using SU8 + Vray 1.49
I tried looking for answers in the forum but I've found.
Someone happened to this thing?
Thank you.

Thanks for the suggestion

thanks for the answer, as I understand it I do not need the very model of the photo, but such a thing, if possible.
