Shadows on Edges on Rendered Mode

Can someone please explain to me why this happens. There’s a random shadow being generated on my wall, for no reason, the room should be dark. My shadow settings are on max sharp shadows, and the self shadowing artifacts is set almost all the way to dirty… please help thank you

Could you please share this 3dm file? Thank you.

This is what I see after opening you file in Rhino 8 for Mac. Whether the Clipping Plane is turned off or on, the issue shown in your screent does not appear.


Could you export your current Rendered display mode settings? Refer to the screenshot below for how to export it. Thank you.
