ARKit Passthrough Material crashes on IOS devices in 4.22

Roggie · April 8, 2019, 8:17am

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:

Create an AR Template Project
Open the BP_Placeable Blueprint.
Set the material of the static mesh to ARKitCameraMaterial found in the AppleARKit Content folder, or create a material that uses the ARKit Passthrough.
Compile and run the application on an IOS device
Start the AR Mode and tap the screen to place and object.

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