Strange fog horizontal lines

Hi everyone,

First time poster here!

Out of nowhere for the first time, I came across these weird lines appearing on the ceiling after rendering. Has anyone comes across this and know the reason why this happens?

Any help will be appreciated!

Andy

Hi there I apologize for the inconvenience. Are the horizontal lines only visible if you activate the Fog option? You might want to check if there are surfaces that have been lighted which cast this shadow.

If it is possible, can you send this file to me so I can test it on my end and assess it further? You may send it to support@d5techs.com and have it titled “Clov-Forum” then briefly describe the issue. Thank you.
