Intel machines render PhoenixFDOceanTex vector displacement differently than AMD machines

[Alex_M]

I've got a scene where I use PhoenixFDOceanTex as a vector displacement map to create waves in an ocean. If I render the image only with the AMD machines (Threadripper 1950X), the ocean renders fine. If I render only with the Intel machines, it also renders fine. If I render with both AMD and Intel, however, I get messed up patchy ocean surface because they render the vector displacement differently. I did some tests with regular displacement (using bitmap textures) and it renders fine with a combination of AMD and Intel machines so it seams that only PhoenixFDOceanTex causes this problem. Let me know if you need a scene and I'll send one but I think it should be pretty easy to test - just make a plane and add a vector displacement to it with the PhoenixFDOceanTex map.

Please check the screenshot below.
EDIT: Sorry, I just saw that I posted the thread in the "General" section. Please move it to the "Problems" section if necessary.

Hello,

Can you send the scene to support@chaosgroup.com so we can check it out?

I couldn't reproduce it in here with the latest official release build. What build are you using?

Hello Georgi,

I'm using Vray 3.60.01 on all machines and the Phoenix2.dlr plugin + vray_phoenix.dll.
I've just sent the scene to the support email. Thanks for looking into it.
