v-ray frame buffer gone!?

V-Ray V-Ray for Maya Issues
1

Using maya 2012 och win 7 x64. V-ray 2.00.04.

The VFB is nowhere to be found. It wont show up during render or when I click on the “Show V-ray VFB” button. ???

Neither will it show during batch rendering.

Have I screwed up some prefs or settings?

It it probably somewhere outside your desktop. Right-click on the VFB icon in the TaskBar and select “Maximize” to bring it back.

Best regards,

Hmm, well it works for new scenes… but for old ones the window simply does not show.
Opening one particular scene the VFB shows up in the top left corner, just enough to be able to grab it. But moving and resizing it on screen does not save when I close it down. Next time it’s in the corner again… wierd!
And, there is no icon in the TaskBar anymore… could this be a result of the qt implementation I read somewhere?

Saved out a scene to .ma and examined the settings… found this chunk, and it looks suspicious.

Apparently, changing the start values to something like 119 472 6 100 100 fixes the problem…

better solution is to right click on the taskbar vfb and Move, then with click on nay cursor key, then move the mouse and vfb will attach to mouse so u can move around :wink: and place it where ever u want

cheers

As I said, with maya 2012 and v-ray 2.0 there is no taskbar icon for the VFB. Not here anyway… :slight_smile:

7

Ah right, we use Qt there… so modifying the .ma file is the only option - sorry about that.

sux :slight_smile: im still on 2011, didnt know that…

cheers

ok, I do hope you implement some sort of fix for this cause it’s a pain to resave as .ma, edit, and then back to mb. for each scene that is not working.

10

Which build of V-Ray were those scenes saved with?

Best regards,
Vlado

I actually don’t know, I have been using different nightly builds since before 1.5 SP1 and forward. I tried writing some mel-code to reset the vraySettings.vfbSA attribute but that didn’t work out…

12

Same problem here, using the latest build. I often get maya crashes if I cancel the render with the Vray Buffer on, this does not happen if I don’t use the vray framebuffer. After that the vray frame buffer for that particular scene does not start anymore. I am on linux.

This works for me in other builds:
