Strange lighting issue

[MichalsAvatar]

Hi all,

Im new to Corona but am loving it so far.
Iver recently started using Corona 5 with 3ds max 2020 and with the house I built, there is a very strange bright white line just under the roof gutter.
Ive built this kind of roof 1000 times in previous renders and its never been an issue.
This area circled in red should be black and totally in shade.
Please refer to the image below. Any suggestions please?

Thank

Are you sure that you don't have spline rendering on and that is actually a spline?

No definitely not.
I actually originally built this house and entire scene in 3ds max using Vray and never had this problem.
It wasnt until I did the Corona converter that this bright white line showed up.
Its very strange.

Would probably need the scene, impossible to tell from a single image as we'd need to know the geometry involved, the materials involved, maybe even the lighting set up, and so on. Could provide descriptions and screen grabs of that, but faster to just upload the scene I would say :) https://coronarenderer.freshdesk.com/support/solutions/articles/5000524006-how-to-report-issues-3ds-max
