Vray 5 - scene changes slightly between repeated renders

[sameyo]

Hello,

I recently upgraded to Vray 5 and have experienced that the scene sometimes changes slightly when I do repeated renders. To be clear: Even though I am using the very same scene in Sketchup and has safe frame activated in Vray, there are sometimes small changes in the rendering result, like as if the camera has moved a few decimeters sideways.

Are there anyone else who have experienced this issue with Vray 5?

The issue is very annoying since it makes it difficult to do post-production effectively (ie. masks in PS has to be updated due to the small change in angle).

I never experienced this issue with previous versions of Vray.

(At the same time I also updated to Sketchup 2022 from Sketchup 2020. Could the Sketchup-version be related to this issue?)

Hi sameyo ,

The issue you've described sounds strange indeed.
Can you give us more details on what exactly is going on?
Images that show the difference together with some more details on the scene setup (camera type, etct.) would certainly help.
Better yet, you can share the actual project.

There was another thread in which a similar issue was discussed.
It might not address your exact case but will certainly give you an idea on how things are handled internally:
