I'm fairly new to CC/iC, so I appreciate your patience.

I'm encountering an issue where some objects appear overly shiny during the rendering of a video. I suspect it's related to lighting, and while I’ve experimented with adjusting the lights, even turning off some additional ones, certain objects remain very shiny.

Is there a way to preserve the same lighting and luminosity I see during editing when rendering the final video?

Example here:

Many thanks for any tips.
