V-ray camera jitter

[magarlick]

Dear all

Can't believe I cannot find a solution to this anywhere, even on this forum.

When I render in V-Ray in 3DS Max 2014, there is jitter between frames. The entire image is displaced by seemingly random amounts from one frame to the other. ANy idea what is causing this? Can it be fixed?

Here is an example of what I mean:

Thanks.

are you sure nobody is using an "educational" version of vray there?

What is the exact V-Ray version that you are using?

Thanks svetlozar. I was on 3.00.04 but I've upgraded to the latest and it's fine now.

Glad to hear that.

Unfortuately we still have that problem.
I started a post about that some time ago (http://forums.chaosgroup.com/showthr...t=camera+shake) and since then the problem occured from time to time.
Maybe about only 3-4 times a year, but it really really sucks. Just today again.
You submit a huge animation job for rendering and the renderoutput of some scenes is completely uselesse because of this unwanted camera jitter.

The strange thing about that is:
- it only occurs a few times a year
- only on some scenes of an animation
- vray is of course licensed. we have 5 floating licenses
- nobody in the whole internet seems to have this problem
- newest vray version is installed. but problem already occured back in 2.4 or so

My only workaround for this is to bake the whole camera animation by setting a key at every frame. But since this is a total destructive workflow it cannot be a solution.
I have to let our render farm render many animations during the holidays next week and it is making me nervous - the render output has to be good in order to meet the deadlines in January...

I hope that this problem will be investigated on and will be fixed asap.

I'm sorry to hear this. Have you double check whether all the software versions are the identical.
Keep in mind that in order for us to fix this issue we would need to replicate this jitter effect in our environment. Therefore we would need a scene that can reproduce the issue and logs from the machines that participate in the rendering process.
