Hi everybody,

I have a very simple scene that a shiny object(with silver or chrome type material) moves and when I render (in mantra or karma) there is a noticeable flickering that goes through its surface. I have tried to change sampling and denoising and following instructions for clean renders but the problem does not go away.

I am not sure whether flickering is the right word but it looks something like waves on the surface of shiny metal.

Is it a common issue? Is it possible to do something about it? (sorry I can not share the scene file).

Thanks for your attention.
