Help me to fix the situation after compiling the game

Hi all!
Tell me how to fix the problem. In the game I create a night scene, the space is illuminated with a flashlight with a texture i.e. the light is not uniform, but as in life with different areas of illumination. So, when compiling a game for Android, all the flashlight settings are lost, it shines like a spotlight in all directions and without any textures. The light from it in the corners of the screen breaks up into some black areas.
Also, trees at a distance turn from 3D into 2D.
