The character's face shows noisy shadows and strange light patterns(lines) in dark place.

In low-light environments, the character’s shadows are severely noisy (circled in blue), while inexplicable light streaks appear on their face (circled in red. The weird “light lines”). This problem also occurs when I use other standalone character models. I am using 9 rectangular lights in the room. Thank you for any suggestions!:slightly_smiling_face:
