Crash when trying to load Mobile Preview

Development Platform & Builds Mobile

Not sure if this is the right place to ask, but not seeing anywhere else that makes sense.

I’m getting this crash when I try to run the game in Mobile Preview mode on Win 8. I’m not a coder, doing a rather simple platformer in BP only. No idea what this means. Any help in how to diagnose and fix would be greatly appreciated.

Is there a tool to check if materials and other rendering related assets are mobile ready? I know that was an issue in UDK, but it would run and just look ugly. This seems different.

Ok, this seems to be different now. I get this whenever I try to play or simulate my game. I can open it in the editor and edit stuff, but I get this crash every time I try to play. Seems I’m screwed now?

Going to try and create a new project and migrate my assets over. Thankfully I don’t have a lot.

I’ll answer my own question. Seems the TouchInterface I created had missing images and this can cause crashes. Strange that it was different crash on my Mac, but removing that and everything worked again. Hopefully that helps someone else.

You need to go to (Settings> Preview Rendering Level) and install Android ES 3.1. Then everything will work. Unreal will begin recounting materials for the phone. Write if this helped. (UE 24)
