[4.9 BUG] Blueprint nodes not firing off iOS devices but works on Windows

EDIT: So after further debugging, its the same issue as my previous issue where event tick is not firing off mobile

but this time I have no idea what is causing it.
Unfortunately it is not producing any error logs on my device so I can’t debug further

I spent a few days trying to debug this issue but I am running out of ideas. I am currently having a bug that I have no idea what is causing it as it only happens on mobile devices (iOS). It works fine on PC and it worked fine on mobile devices (iOS) during 4.8.

It has something to do with rendering that is somehow not doing it correctly as printing the results show that it is visible but in game it is not shown at all. (Only on mobile devices iOS using 4.9)

The node in question:

Crackable Egg Sprite, Crackable Particle, Crack Sprite are all not visible initially and will be toggled to visible during this phase as shown in picture below (Windows version), however the iOS version does not toggle even though it still prints out true when I get the visibility from Crackable Egg Sprite.

*Please ignore the fish differences, they are randomly spawned for testing purposes and have no effect on eggs.
As you can see, Windows version scales up the egg properly and shows the crack sprite:


But on iOS, the egg gets stuck at its initial size and never shows the crack sprite nor move to the center of the screen:


If any staff can look into this, I will gladly send my project file and steps to reproduce the issue. Thank you in advance.

Hi ,

Please post your project and I’ll take a look at it. You can mail me directly .porter at epicgames.com if you don’t want to post the link here.

It would be extremely helpful if you can modify the contents so that the issue occurs immediately when the level loads.

I’ve emailed you the modified project zip file (you can spawn eggs directly without having to go through the game) and steps to reproduce the issue. Thanks for looking into this.

Thanks , it might take me a couple of days but I’ll have a look at the project and see what is going on.

Cheers
