Vray frame buffer missing

[evanerichards]

The vray frame buffer has gone missing.

I've tried this trick:
setAttr "vraySettings.vfbSettingsArr" -type Int32Array 0;
Which worked earlier this morning.

I tried deleting some nonesense in the .ma file.
I deleted my prefs
I restarted maya, and my computer.
I unloaded and reloaded vray.
I reinstalled vray.

This happens even if I just start maya and create a cube and try to render it.
I'm on vray 3.4.06 I think. Maya 2017



I still cannot see my frame buffer. Until I can, I can't do much.

Any ideas about other ways to fix this?

Have you tried this mel code:

vrayShowVFB;
window -e -topLeftCorner 1 1 vfbPanelWindow;

[evanerichards]

No! Haven't tried that. When I'm back at work tomorrow I'll give it a shot.
Thanks!

Have you tried this mel code:

vrayShowVFB;
window -e -topLeftCorner 1 1 vfbPanelWindow;

Didn't work.

When I type in that code it gives me this error message:
// Error: line 2: window: Object 'vfbPanelWindow' not found.

Ok. So I've figured out the problem...but do not have a solution.
After pulling my hair out for literally hours trying to figure out what is wrong, someone suggested plugging in a second monitor. I did. And lo and behold, there the vray frame buffer window sat like it had always been there. I moved it back onto my primary window and restarted maya. Renders to my second monitor. A monitor I didn't even have until the frame buffer went missing.

How can I fix this? Is there a way to specify what monitor you want your frame buffer rendering to?
There is a weird workaround that I'm using in the meantime. I click the "Show vray frame buffer" button and while it has focus and before I click anything else I hold down the windows key and then press the left arrow three times and that'll move it back onto my screen. But this isn't a great way to work.
Any other ideas would be appreciated.

Thanks!

for ($window in `lsUI -windows`) {
    if (`window -q -exists $window`==0)
        continue;
    if (`window -q -mainWindow $window`!=0)
        continue;
    window -e -tlc 0 0 $window;
}

This ?

One cause of this happening is when you go from a 4k monitor to a 1k. A way to avoid it completely is to not use a floating window, but have it docked in Maya. Not sure if the VFB can do that.

Code:
for ($window in `lsUI -windows`) { if (`window -q -exists $window`==0) continue; if (`window -q -mainWindow $window`!=0) continue; window -e -tlc 0 0 $window; }

this is now implemented as a VFB functionality in the latest official builds. Right click on the VFB icon > Reset VFB position

you can dock the VFB in a viewport space: Panels>Panel>V-Ray Frame Buffer

I do not see that menu option in Maya 2017 with Vray 3.52.

Is this in latest nightly? I am on the latest official build and couldn't see this option in my Panels>Panel menu in Maya 2017 Update 3.

Will give it a shot.

Unfortunately this feature is not available in Maya 2017

Unfortunately this feature is not available in Maya 2017

Can you specify which Maya version supports this feature?

[Zdravko.Keremidchiev]

All Maya versions except 2017

[Mihail.Djurev]

All Maya versions except 2017

We'll keep the panel functionality disabled in future Maya versions as well.
