URGENT - IOS: App close after start

Hi,
we are building a subway architectural 3D project with a menu to change some materials. It works well on an Ipad Air 2 until we add more textures and materials. We have not error on the deploy but when we start the App, after some seconds of black screen, it closed! We think that is for the resolution and number of maps but it make the identical behaviour on ipad Pro 12,6 that have 4GB of System RAM instead 2 GB on iPad Air 2. Is sure that Unreal is considering the Ipad Pro 12,5 and is not deploing for the old Ipad Air2 that have the same name? I write this because i have modified the .ini Target hardware for better antialiasing on Ipad Air2 and the version with less maps has the same better antialiasing to the Ipad Pro 12,5 too!

I think could be possible resolve with straming/MIP of high resolution textures but how to optimize this for IOS?

Thank You

Hi ADL67,

If I understand you correctly, your App used to run on iOS devices but now, after adding textures and materials, your app will start but after a few seconds, the screen goes black and closes.

The iOS Devices you are testing on are:

  1. iPad Pro 12.9" (4GB Ram) Apple iPad Pro 12.9-Inch
  2. Apple iPad Air 2 (2GB Ram) Apple iPad Air 2

You are concerned that the device with 4GB RAM is performing the same as the device with 2GB RAM. However, while the greater amount of RAM allows you to have more processes running at one time, it does not significantly increase your display quality. If you compare “Video Support” on both of these devices (linked above) they are identical.

Hence, optimizing your textures and materials will correct the issue for both test devices. Please review these links regarding reducing APK size and optimizing textures for mobile devices:
