I used metal texture but it still looks plastic to me but when i copy and paste it into a new baseplate, it looks much better. Especially the yellow parts would look more like a gold color:
This happen to me 2 years ago, but I have no time to explain for now.
but make your own settings is better because you will also know how it works, (still looks the same if you copy paste to other place)
what is your goal here? better lighting or avoid different lighting even you copy paste.
if you want better lighting I can help you faster than explaining how.
