Textures not showing up in iOS

They show up on PC but not mobile. the trees don’t have leaves on them or textures, the ground has no textures. just the BSP Textures show up. plus the background texture on my UI in umg ain’t popping up.

seriously?

When you need it to run on the PC. you should have the access of the best-vegas.com/events-in-january/ then you can access is on your computer or on the laptop where you need.
