For one, there’s now too many point lights in the area. It’s actually surprising at least one of them doesn’t have a red X over it.
For 2. Since none of your screenshots include the whole view port we don’t know that light and reflection captures are actually built.
they sure don’t look it, the metal panel should be reflecting the blue hues even if black.
First check your material parameters. Make sure you have the right settings on default lit. Default lit, etc. See if you accidentally turned on or off any value you shouldn’t have.
Then Put a multiply x1 on the metal map and click the down arrow. shoot a screenshot for us (we can sort of tell what’s blue and what isn’t, but still).
Same for roughness just to double-check it (It seems like it is all set to 0 from the little image. Which is probably fine).
also, put a .5 static value in specular.
It’s the same as the default, so it shouldn’t change anything, but it’s good practice so you know visually you haven’t set it to something.
Last thing to check is removing the AO.
Still pretty sure your material is OK though. And your light building isn’t.
