Hello, I have a serious problem with speckles this time. Mostly, these are generated by HDRIs with values way above 1. In this case however, it is different. I have a car part with a silver metallic paint. The paint is using glossy reflections, reflection depth for the paint is 5, glossy subdiv is …
