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"

ARKit Passthrough Material crashes on IOS devices in 4.22

Using a material with ARKit Passthrough material node on static meshes will crash the application on IOS devices when the mesh is displayed on screen. Tested on iPhone 7 running IOS12 compiled with UE4.22 Development settings.

Steps to recreate:

  1. Create an AR Template Project

  2. Open the BP_Placeable Blueprint.

  3. Set the material of the static mesh to ARKitCameraMaterial found in the AppleARKit Content folder, or create a material that uses the ARKit Passthrough.

  4. Compile and run the application on an IOS device

  5. Start the AR Mode and tap the screen to place and object.

Did anyone manage to get this working on UE4.22?

Product Version: UE 4.22
