V-Ray RT Preview Animation Not works.

[E-Lahoz]

Hi all.

I'm testing V-Ray RT Animation Preview, but only makes 1 frame and stops the Render (The animation is 94 frames)
... I try with CPU and CUDA but not works for me.

3DS Max 2014 SP5
V-Ray 3.00.03 NFR

Any solution?

Can you try a newer build? I think we fixed something in that regard.

Best regards,
Vlado

Thanks Vlado, I go to try the new build now.

Thanks Vlado, I go to try the new build now.

Not works Vlado, the same as 3.00.03 with 3.00.05, only makes 1 Frame (start frame only).

It's fine in my tests, can you send me your scene ? peter.matanov@chaosgroup.com

[E-Lahoz]

Scene sended.

Hi all,
I have the same problem, also with a simple scene with only a teapot. The problem persist with max 2014 and 2015 with vray 3.00.07. Have you solved somehow ?

Thank you

No Sprawl, for now I can't solve it.

E-Lahoz the scene you sent me is working flawlessly, Sprawl I'm waiting for yours at peter.matanov@chaosgroup.com

Same problem now. I'm testing RT Animation Preview in Production Render, but only makes me frame 0... and when I close and open the RT animation Preview Settings window, not works. I need to restart 3DS Max to try another time... and not works...
* 3DS Max 2015 SP3
* V-Ray EDU 3.10.03

Same answer buddy Works just fine in my tests (same max and vray versions). Send me your scene and I will test it again.

Hi again,
I have to do a preview anim with RT but again the same problem: render frame 0 than block on frame 1. I try to restart max and try with an empty scene and do the same so it's not a scene problem but something else.
The strange thing is that 2 days ago it worked, but i don't change anything on my workstation
The problem is both CPU or CUDA mode

3DS Max 2015 sp3, vray 3.10.03, quadro k5200, dual monitor (don't know if this could be a problem)

I don't know what to do, but help me please, because i need to do this preview animation

Thank you

You have two other options.

First one is to simply set V-Ray RT as a production renderer and just render as normal animation (make sure you select CUDA as the engine if you want GPU render).

The second option is to render with V-Ray Standalone. Right-click in the viewport that you want to render, and select ".vrscene exporter", enter a file name in the first field, something like "c:\temp\test.vrscene", turn on "export animation" and select the wanted frame range, then click "Export" (not "Export and render"). After that, open a command prompt (Start menu > Run... > type "cmd" without the quotes), and on the command prompt, type the following (this is just one line):

"c:\Program Files\Chaos Group\V-Ray\RT for 3ds Max 2015 for x64\bin\vray.exe" -scenefile=c:\temp\test.vrscene -imgfile=d:\temp\test_out.png -rtengine=5 -rtsamplelevel=100

where you need to replace the scene name and the final image output with suitable values. -rtengine=5 means the CUDA engine, and -rtsamplelevel is the number of passes that you want.

Best regards,
Vlado

Hi Vlado,
I didn't try the first option, but the second one works good!

Thank you

Sprawl

Ps.: what do you think could be my problem on vray rt animation preview ?

[Sprawl]

Hi Vlado,
I see a little problem: vray render the anim, but overwrite the same image file, how could i tell him to generate image frames ?

Thank you

Sprawl

Edit: Ok I found the standalone help file. I added this command: "-noFrameNumbers=1" and now works
