Unreal Engine 4.18 Preview

Having some problem with ARCore/Tango.
Make a new fresh project, enable ARCore plugin, packaging for android fails:
on > Could not resolve all dependencies for configuration ‘:app:_debugApkCopy’.
1> > Could not find com.google.tango:lighting_estimation:0.0.0.
1> Required by:
1> :app:unspecified
1> > Could not find com.google.tango:tango_java_lib:0.0.0.
1> Required by:
1> :app:unspecified

Seems to me that maybe the dependencies declared in the GoogleARCoreBase_APL.xml might not have been included… unless I am missing something.

p.s. this happens with gradle, tried switching over to ant, but that failed even more spectacularly

Double click on Blueprint “ARLine Trace from Screen Point” crashes the Editor.

And, I have no idea on how to get AR to work in 4.18. Can someone please give a little guide. Much needed! Thanks

Agreed, I see some pieces like Shin_ji mentioned but not all of them. We need a sample scene setup with GameMode and Pawn so we can fix up our project.

Should I use Xcode 9 instead of Xcode 9 beta 3? Or should I upgrade macOS from Sierra 10.12.6 to High Sierra 10.13 GM candidate?

However, following simple AR setup to place some cubes into the world I get camera feed and whenever I flip the phone aspect ratio gets messed up. Would apreciate any info in terms of camera setup in AR.

I wrote up details on a fix for the camera issue here https://forums.unrealengine.com/development-discussion/ios-development/1358295-arkit-4-18-preview-1-official-ios-11-and-xcode-9-camera-feed-?p=1358696#post1358696

Cheers,

We are making a game with random generated levels on 4.17 where I have to fake indirect lighting with lightmaps
(we load sub levels as rooms).
Is possibile to move the level and the whole indirect lighitng after bake with the new lightmapping system?

Check this AnswerHub post about that. I even made a pull request to make it possible.
https://answers.unrealengine.com/que…l-instanc.html

I don’t know yet if the volumetric lightmaps in 4.18 still have the same issue, I’ll have to download the preview to find out.

58

Amazing release as always! Thanks Epic!

59

Does anyone know/tried to see the impact of the new update on physical animations and hits and reactions? Just as soon as I found some material to map my reading list to get to understand this, this new update. I hope it makes things easier. Anybody can comment?

I have upgraded from Xcode 9 beta 3 to Xcode 9, still doesn’t work with 4.18. Or should I upgrade macOS from Sierra 10.12.6 to High Sierra 10.13 GM candidate?

Totally same procedure, why it works with 4.17, but no icon and crash with 4.18? Can anyone help me with this?

63

When is this problem fixed?
The most basic functional issues, the priority should be relatively high.
