IOS build crash on startup, but only Ipad not Iphone

Hello,

I have packaged a build (tried both shipping via testflight and just dev package) in Unreal and now it works perfectly fine on my Iphone but on my Ipad it crashes immediately after the splash screen.

I managed to get a symbolicated crash log, but I have clue about finding whats wrong.
Could use some help here please.

Since it might be related, my phone is on IOS 15 whereas my IPad is on IPadOS 15.1

Set forward shading to ON.

That unfortunately made no difference :confused:

Try set Mobile MSAA to NOMSAA, if it working, then you must set other rendering settings,but i dont remeber what.

Hey @Cektantwork ,

Mobile MSAA was set to NO MSAA all along, so that did not help either I am afraid. But thank you so much for giving me some pointers to try at least.

You can try set desktop render to enable and mobile render to disable in ios setting, if it work than you must change some rendering settings. I did some magic like this throughout the month and all working.Sorry for such vague advice, I really don’t remember the exact set of steps. But my problem was in rendering, but I don’t remember exactly what values.

Also that did not change anything unfortunately.

I seem to have narrowed it down to virtual texture support for mobile. I am using UDIM atm for my textures and have therefore this setting enabled. When I disable it, the crash on Ipad is gone.

The weird part though remains why it does not crash on my Iphone 8, even with the setting still on.
