Render elements shuffle around

[robdeja]

I wonder if anyone can help me with this problem I'm experiencing with V-Ray 3.50.04.

I'm rendering out animation frames through Deadline 9 (scene submitted via RPManager) and I'm finding that my render elements are shuffling around on about 50% of the frames.
I'm using the V-Ray frame buffer to render to EXRs and embedding the elements.




I'm not sure where the problem lies but I've tried the following:

I updated Deadline to version 9.0.6.1 as I was aware that there was an issue with V-Ray elements on earlier versions so I hoped that this might be related.
I'm running the latest available version of RPmanager.
In Deadline submission I've made sure that it's restarting the renderer between frames and that task size is 1.
It's not specific rendernodes that this occurs on, it's random.
I've not experienced this issue on any other scene before but my workflow/settings are the same. I've tried merging geometry into a new scene.

Has anyone experienced this before or can think of anything else I might have overlooked before I start changing my workflow to work around this?

Thanks,
Rob

OK so I've spotted the cause of the problem - there is a duplicate VRaySpecular element. Easy fix. Phew!

Cheers,
