Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

4.20.1 IOS ARTemplate Crashes after splash screen

I started the bare ARTemplate project and set it's world game mode to the BPARGameMode

I then set my provisioning profile and cert, and turned on automatic signing, the same thing i did with the third person template.

The ARTemplate crashes after the splash screen, the Third Person template does not crash.

I am using xcode 9.4.1 and ios 11.4.1

Anyone have this working?

Product Version: UE 4.20

No Idea how but the plugins for ARKit were disabled. I thought I had enabled them! it works now but only the first launch, if i close and launch the app from the ipad, it doesnt work.

Ahhhhh, thanxx a million !! I doodled an hour to figure out why my app crashes all the time until i found this.

In case anybody else is struggling with this, it kept crashing when I was trying to package the project when I had the ARKit plugin enabled, but figured out I wasn't running the latest XCode 10 beta. Fingers crossed, seems to be working now.

We also have the same problem... The latest Xcode doesnt fix anything, the app only opens to the splash screen and immediately after this it crashes.

It worked in my case BEFORE the update to ue 4.20.2 and ios12. Now the app prints an error like: "Failed to open descriptor file"

Same, ios12 seems to have broken my project as well. Shows the splash screen on iOS and then crashes.

You're a life saver. Thankfully I've only wasted about an hour wondering what was going on. Just updated the ARSample project to 4.20, and the plugin was disabled by default! Madness!
