Renders randomly turns black / blank - Render Elements

In some scenes my render randomly shows up black (not rendering anything). I know it has something to do with render elements, seeing as the problem disappears / reappears whenever I add, remove or edit my elements.

Several people at the office has had the same issue, but no one knows exactly how or why it happens. Even after it’s “fixed”, it randomly happens again without warning.

Is this a known issue? any solutions?

Can you please specify Corona and the host software version?

Thank you.

3Ds MAX 2020 and Corona 5

Could you please archive your scene and upload it using our private uploader?

Private uploader: Chaos

Please let me know if you choose to do so, we will investigate the scene and offer possible solutions.

I cannot share my files from work unfortunately, but we found a “fix” for it that seems to work most of the time: saving/closing and re-opening the scene again

I understand, hm sounds some issue with the scene definitely. I would suggest you check the project with Sini forensic, or prune scene. Make sure all 3rd party plugins are updated and there are no incompatibilities. I am afraid at this point I can only guess, should the issue persist or if you manage to isolate it in a shareable scene please do write us back.
