Some objects wont show up in render

[Wigstrand_Digital]

Hi.

I have a really strange issue. I have this scene that I have worked on for a while. Today I'm about to do I final render, and suddenly the majority of the objects wont show up in the render.
I use 3ds max 2019, Vray Next update 3. I also use Multiscatter and Autograss. I have 64 GB RAM, so that should be more that enough...
I try to render A4 300 DPI; so its not that big. But when i render in smaller resolutions, it renders just fine....

I hope someone can help me with this issue.

Best regards - Tobias

Really, no one has a clue? Tried all day to get around this, but nothing....

I would first try to backtrack which element is suddenly causing the majority of your scene to not render. Start to only enable your standard geometry and see if this works, then start to enable all your different scatters one by one. Once you found which element is causing the issue (multiscatter, autograss, etc) eliminating the problem would probably be more easy...

Have you checked your plugins? Maybe a license is failing.
