railclone forestpack disappers/ does not update in the camera sequence rendering

[filip]

Hello, 3dsmax 2024.1, vray 6.1, railclone lates or beta (happens in forestpack latest but less often) rendering GPU

I have an architectural scene where I am rendering more views through animated camera (garden view, backyard view, aerial view... fr00, fr01,fr02...).
fence, railing, curbs etc... are railclone objects and they randomly disappaer when I render all the sequence. Something like the scene does not update correctly before the render starts.
This happens as well when I skip to frame 1 or 2 etc and hit the single frame rendering. This Happens in the backburner stripped image job as well, some stripes are ok, some without railclone (all rendered on one machine no network included).
I know this could be an itoosofts issue, I wrote there too...
Any advice here?

Many thanks

Hi, thanks for posting. It is very important to know if the issue is happening locally or only through a network rendering. Could you test this? Also could you try to collapse your rail clone object to a mesh?

Hi Vladimir,
this happens locally and collapsing to mesh is possible.
I sent you PM with the simple scene.

itoosoft: With your help, we've been able to reproduce this behavior here too and we'll continue analyzing this issue - it'll need to be investigated more in deep by our main developers. Just let me mention, that the GPU /implementation is done entirely by the Chaos Group team and we have a little influence on their development roadmap.

Hi, thanks for the follow up. I will review your scene and get back to the thread.
