Hey, Im rendering a chaarcter in 3Ds max, using the arnold renderer but i get these light artifacts (Black spots) when I render only certains parts por the model, from certain angles. As you can see in the screenshots, the most obvious one is in the pants saddle, but also the belt mettalic part gets some of that.

I´m using a PBR Material for the model.

I don´t know if it´s a render settings problem, material problem or even something with the 3d topology. Does anyone have a clue on how to fix this? Thank you very much in advance.
