mapping problem

Hi

I deployed a project on my android sony z1 phone. but something wich is alright on pc, when goes to phone gets wrong!

although before exporting from 3ds max i created right uvs for every object in the scene when i open the program on phone it seems that the map is copied just once and it is not tiled!
i think these three reasons may cause this problem:

1- hardware problem and poor performance of my phone (scene has 65k polys :’( ) but there is not any lag or jumps in vr. it works fast.

2- problem in transferring data from unreal to phone

3- unsuitable uv for deploying on phone.

i will send you photo from my phone and my pc to see the difference.
