Probably i dont understand you right but i dont use PhysicsX c++ code and my project is in blueprints.

Hello,

Based from what I understood in your log file, it seems that the cause is coming from your PhysicsX c++ code. This may be a code or a line of code that may not be support during executable. I also experienced this wherein when I use PIE, I have no issues but when I already packaged the problem I encounter issues and it was because of a code wherein it is not permitted to be executed in a build file.

Hope this helps you

hmmmm I’m not sure though but when I was able to look in your log file I saw that the crash started in the PhysicsX

Ok I already know what the problem is. I myself have encountered this one.

You have assets that are still inside the project folder but is not recognized by the engine.

Try these steps:

  1. Fix redirectors
  2. Delete the objects that have the warning when you build your project. Make sure that you open your message log when building so that you can determine where are these assets are located. In order for you to delete these you should go directly to your project folder (this is not in engine) then delete them.

See attached file for guide.

Hello Tenjer,

It seems like the major problem here is related to some marketplace content that you’ve downloaded.

MainFrameActions: Packaging (Windows (64-bit)): UE4Editor-Cmd: [2016.08.12-10.38.40:205][ 0]LogPackageName:Error: DoesPackageExist: DoesPackageExist FAILED: ‘/Game/Unreal Engine 4 Market Place - Modular Desert Ruins/DesertRuins/data/Content/DesertRuins/Levels/lvl_showroom’ is not a standard unreal filename or a long path name. Reason: Name may not contain the following characters:

Please be aware that no spaces are allowed in folder or file names that are located inside of your Content folder. You’ll need to remove the spaces from the folder name “Unreal Engine 4 Market Place - Modular Desert Ruins” to be able to package. There may be other issues as Alson mentions, but this will continue to block packaging until it is fixed.
