How to make gun mesh lighting be brighter?

How to make the lightning/shadows not so harsh on my weapon, and make my weapon brighter, sort of?

Call Of Duty Modern Warfare II 2022 - All Weapons - YouTube

I want my weapon’s lightning not be so dark, I want the lightning to make it brighter so I can actually see the weapon and the material on it at all time when it’s day outside…

I don’t know what should I change in my material to achieve something like COD guns achieve

Here is how my problem looks:
