unwanted shadow artifacts when creating animation

these shadows appear during my animation. there are no lights that create these shadows and the shadows move during the animation as if the light source is moving. they do not appear in my saved scenes


Hi @marcoguidetti

Are the curtains attached to the walls or do they have a gap in between (that may be the cause of the issue and the light source is the sun)

Thank you.
