My game in mobile looks totally different than in the editor



I am new to unreal and I need some answers to make my mobile game look better.

Is the preview rendering level in editor set to android or ios?

What about quality settings? Editor and packaged game usually uses different settings by default.

Thanks a lot for your response. when I set preview rendering level to android now the editor is showing as in mobile But how can improve rendering in mobile?

I am not familiar with mobile development but I assume you should do most of the work in materials so if you want a fog effect create a sphere mask in the material.
