So far I am able to package and launch AR apps without a mac on 4.18 prev4 as well. I’m stuck on how to get the camera on the phone to activate the background. In previous versions there was an “Apple ARKit Camera Texture,” but in prev4, it appears to be gone. How do I get the camera to project onto my skybox now?
Update: Nevermind. I figured it out from this post: https://answers.unrealengine.com/questions/708873/using-arkit-with-418-preview.html
