Vray Proxy and missing bump and displacement

[puha0941]

I am currently rendering a big scene that I could not render before using proxy.

I have water in my scene and it seems to me that the displacement and bump on water texture is missing?!

Is this a known issue with proxies?

Thank you

Hello there,

Displacement on Vray proxy is not supported at the moment - however bump textures should work normal.

Thanks for your reply
Do you know when the fix is going to be release for the two-point perspective VFB and Rhino viewport offset issue?

Unfortunately we are not able to give any time range for this fix.
The only thing that we can do is the change the priority of this request, but we need to know how urgent is this.

Thank you for the reply!

I believe this is very urgent issue for those who uses vray especially in the field of architecture. Two point perspective renderings are very crucial in architectural visualization.
Yes, please!

You can use lens shift to turn your 3point into 2 point. You just don't get to see what it will look like in the viewport first, because it happens during the render in Vray, not in rhino. But do a quick test render to verify the composition and it's fine.

i am very glad that there is a way around this issue because I wanted to make a render with line drawing overlay.

Could you kindly walk me through the process? I am not very familiar with the lens effects in vray. All I use really is the ISO value

First, do I leave the rhino viewport at perspective or two pointperspective to begin with?

Thanks Fooprobe!

Use a 3pt persp window. Turn on physical camera. Change lens shift number to be non-zero, usually less than 1 unless you are really tilted. If it bends the lines the wrong way change to a negative number.

And this button script from Gijs calculate the value:

-_RunScript (
Call guess_shift()
Sub guess_shift()
Dim view : view = rhino.CurrentView
If Not rhino.IsViewPerspective(view) Then
rhino.Print "can't calculate vertical shift for orthogonal views"
Exit Sub
End If
Dim cam : cam = rhino.ViewCameraTarget(view)(0)
Dim tar : tar = rhino.ViewCameraTarget(view)(1)
Dim cam_a : cam_a = cam
Dim tar_a : tar_a = tar
cam_a(2) = tar(2)
tar_a(2) = cam(2)
If rhino.Distance(cam, tar_a) = 0 Then Exit Sub

Dim shift:shift = rhino.Distance(cam, cam_a) / rhino.Distance(cam, tar_a)
If cam(2) > tar(2) Then
shift = -shift
End If
rhino.Print shift
End Sub
)

Right! It's in your toolbar!
