I HAVE PROBLEMS WITH PACKAGING. When i start packaging my project the are a lot of warning messages like this : Can not attach to C/…/…/…/landscape auto material/…/ and error message : BUILD FAILED PackagingResults:Error: Error Unknown Cook Failure.What should I do?
(probably the problem in LAM pack for ue4)

I cant do it now but I will do in a few days.

Hello,

Please provide your full output log from your project’s Saved->Logs folder.
