Material on mobile render black? help!

I am making a game for android. It is a car game where the track is generated through blueprints. the track is spawned ahead of the player. When I run the game on a mobile the track and everything along with it is rendered black, except the car and sky-box. But on PC Everything is working fine, It also works fine on extremely high end mobiles like Xperia Z2. Please Help!


Mobile graphic has many limitation. For your scenario you must use dynamic lighting. Because your environment is not Static Meshes. Or you can bake lighting in 3d program into textures and attach them to Unlit shaders in UE4.
