Hi Anis,

> Can I add more light so the 3D model will look more brighter ?

I think there may be an option to put specular highlights which would brighten it further.

But the main reason this one looks dark-ish is the base surface colors are dark, the best way to brighten it would be to have some brighter base colors rather than dark base colors.

There is already quite a lot of light being applied to it, I don't think that you will typically want to put much more than that in, otherwise things that are brighter colors will become very washed out.

But probably specular highlights would be what would help in this kind of case.
