Importing Error From 3D Max

I have a laptop (modeled in 3D Max)
It have some like 100 boxes (for keyboard) but my problem is :
The screen i can see just from the back not from the front
I can’t see the keyboard…
Sound like a stupid question but i really need help…Ty.

I am not sure but I think you need to check if your polygons(normals) face to the correct direction in max, or maybe you should check your export settings and see if you flip the normals of your polygons.
