Hello there,
One thing that stands out as a potential to me is that the MovieRenderQueue (MRQ) configuration is has forced LODZero. If the editor is allowing the use of LODs, it’s possible that the MRQ is just pushing the polygon count too high if that is the issue. What is the primitive count in editor with stat unit?
Secondly, are you seeing anything in the logs that may be related to this?
As an aside, what GPU vendor is in use? There can be minor differences in how the drivers allocate the acceleration structures, but ultimately it is unlikely to be the issue.
Best regards,
Chris
