Vray 2.0 RT on Backburner

V-Ray V-Ray for 3ds Max Issues
1

I just tried submitting a RT job to backburner. The nodes do launch 3dsmax, but then just hang on the first frame while displaying the render message “transforming vertices”.

Funny thing is that a partial render does actually appear on one node, but then also just stops.

Both CPU and GPU give the same result.

Any ideas?

Do you run the backburner server as a Windows service, or manually?

I start it up manually (have a shortcut placed in the startup folder).

4

Does it only work when the server is running as a service?

5

No, in fact it is less likely to work as a service; it works fine here though across several machines when I run the backburner server manually, so I’m not sure where is the problem. Does it eventually render an image if you specify low number of paths per pixel?

Stebbing3D, you using the 64-bit version?
How is it with the 32-bit version?

Thanx

Yes, I’m using 64-bit - didn’t try 32-bit version yet..

Just did another couple of tests with performance settings at 64/8 and 256/64 - but that doesn’t seem to make any difference. Only the first node to start the renderjob actually outputs anything - the others still just hang on the first frame..

Another pretty strange thing, is that when I select an animated camera - RT only renders from the first position of the cam? It somehow ignores the camera animation. This also happens when rendering locally.

So I could reproduce the multiple machines issue; will be fixed for the release.

Thanks for the pointer on the camera animation - will check it out.

Perfect Vlado - you just made my weekend a bit happier :slight_smile:

Many thanks to Vlado and the rest of the Chaosgroup team - Backburning with 10 x 480’s is now finally a reality!!

Allright - so, it’s working on Backburner. But when I attempt to render out PFlow animations - RT only outputs the first frame of the particle animation and then just render static particles throughout the rest of the animation.. It’s somehow not really picking up the keyframes set in PFlow..

12

Did you turn on the “Particles” option in the RT settings?

Best regards,
Vlado

13

Yes, it is on - and RT does render the particles.. Just without any animation of the particles..

14

Can you get me your scene to vlado@chaosgroup.com? It works for me on a simple test.

Best regards,

Any update on this problem? Could you replicate the problem using my scene?

If anyone else want to give it a try - a simple test scene (Max 2011 x64) can be downloaded here:

So, when rendering a still the particles look fine - but as soon as I attempt to render a sequence, there are no animated particles..

Thanks I can reproduce this issue here and we will be looking at it. For the time being you can also generate the animation through the “Render > Make V-Ray RT animation preview” menu through the ActiveShade renderer.
