ARKit 4.18 preview 1 - official IOS 11 and XCode 9 - camera feed red?

[ND_Dwight]

This gets ARKit working with ios 11 and xcode 9 official versions. But the camera display will be RED.

It works, just as you said. Thank you! And you may be "happy" to hear, that my camera display is also red.

Do you mind telling me how you got it to work?
I deleted the ARKitCamera and the texture, from 4.17.
In 4.18 I now export to iphone and run the app, but I see a white background instead of camera feed and can not move the camera...

-EDIT UPDATE This has now been updated after fixes below so the camera should now work fine!! Thanks to Skyphyr and Omigamedev

Install 4.18 Preview 1.
Create new project -> blank -> set it to mobile, no starter content, scaleable 2d/3d
Apple ARKit plugin should be enabled as default but just double check under plugins.
Setup IOS so your provision/certificate are present. Setup bundle display/name/identifier
Change minimum ios version to IOS 11, I've kept Metal v1.2, Frame rate lock to 60fps
Under Project settings enable 'Start in AR'
Under Additional Plist data add this: <key>NSCameraUsageDescription</key> <string>This application will use the camera for AR</string>
Restart if prompted

Enable Show Engine Content and Show Plugin Content from the view options in Content browser
In your game world you should have a Directional Light (mine set to static)
Create a new Blueprint of type pawn and add a camera component to it. Go to the Camera component details->Rendering Features -> Post Processing Material, where it says Array click on the +, from the dropdown Choose ->Asset Reference, click on none, now in Browse type in ARKitCameraMaterial, select this.
Click compile
Now add this Pawn to your world at position 0,0,0
Build lighting if necessary.
Connect your iphone/ipad and Launch
Game should start with camera now functioning.

Hi, I've managed to get ARKit working on official ios11 and xcode 9 using 4.18 P1 on iphone 6s however the camera feed now has a red tint to it, could any of the devs give any pointers in getting the camera to show as 'normal'? Steps were: Creating an unlit 2-sided material using the ARKit Passthrough Camera node (Texture Y and const coord 0), using a regular camera component in my pawn and have enabled 'Start in ar' option from project settings. Thx.
