Vray 5 ignores animated objects when rendering multiple frames

[oliver_zink]

switching the visibility of an object on off does not work if you render two frames. In the first frame the object should be visible and in the second it should be hidden. If you render both frames the object will be visible in the second frame. Same behaviour when objects should move.

Hi oliver_zink, how are you animating the visibility of the objects? Can you share a simple scene which reproduces the issue so we may take a look?

[oliver_zink]

In this scene the object 'Grafikwand hinten' should be visible in Frame 00 + 01 and invisible in Frame 02.

This seems to be an issue we have overlooked - I have logged it for fixing.

Same here - just found out. Animating object visibility. Please fix quick.

Can't believe how much basic functionality Vray 5 still missess...

The fix is already on its way for testing and may be available in the stable builds in the next few days.

Same here! Very important to change soon. See pic in the attachment.

cool water...

Thx, but the problem comes up when I change the visibility of the sky. Frame 1 (invisible) and frame 2 (visible).
Rendering frame 1+2 computes the issue with the stribes (picture). Rendering just frame 2 is fine.

Fingers crossed (Just tested build from today, but guess it's still too soon)

Fixed in today's build - thank you!

oliver_zink ,
as it was already mentioned the issue was fixed and the fix is available in the latest stable builds on our nightly server. Here is a link for download:

This issue is unfortunately still there on deformed geometry.
So switching visibility on actual geometry (it does work on native cube or sphere) with a deformer on it will not work.Once the object is visible it will remain visible in all following frames.
Hope this is fixed soon. Since I can't work with vray5 now.. my project requires this.

[deyan.hadzhiev]

Hi floris_drupsteen, the visibility options of the deformer object do not have effect on the deformed object, so animating them should not have any result. If you are trying to animate the generator flag of the deformer object - this is different than the visibility and is a separate issue.

[floris_drupsteen]

Hi @deyan.hadzhiev,
thank you for your reply. I'm not trying to render the deformer object.
I've animated the visibility of the sphere, cube and sphere.1
This goes as it should when the twist deformer is not enabled. But when it is enabled the geometry does not disappear anymore when visibility is set to "visible in renderer: off"
