How to light actors spawned at run-time on android?

I have a level in which actors are spawning at run-time . I m trying to use skylight for lightening the shadows. It’s working fine on pc but not working on android . I am stuck with very dark scene .I would really appreciate if someone can tell me how to make shadows lighter on android for actor spawned in game . Thank you .

I would like to know this myself. My mesh looks great in the editor but extremely dark on mobile.
