World has no context

twistedpancreas · March 7, 2017, 11:48pm

Hi there trying to package my first VR Win64 exe and I’m getting this error

Program.Main: AutomationTool exiting with ExitCode=25 (Error_UnknownCookFailure)

When I look at the warnings, I’m getting a lot of “World has no context!” and “Failed to parse argument “LevelName” as a number (using “0” as a fallback). Please check your format string for errors: “Edit {LevelName}”.” messages. Have I stuffed up my levels somehow?

I also notice when it’s packaging that my level names are replaced with UEDPC at the start of the level’s name (see screenshot)

My log is attached.[link text][2]

Hello twistedpancreas,

I have a few questions for you that will help narrow down what issue it is that you are experiencing.

Quick questions:

Can you reproduce this issue in a clean project?
If so, could you provide a detailed list of steps to reproduce this issue on our end?
Could you provide screen shots of any settings/blueprints that may be involved?

Hey there Rudy, ok so I started a new VR project and duplicated the MotionController Map and renamed it “start”, I then duplicated “start” and named it “fac”.

"start’ is the persistent level as below…

In “start” I removed all meshes and left everything else. In “fac” I removed everything but the meshes. In start for the blueprint I put the following…

I then went to Package Project > Windows > Windows (64 bit) making sure Start in VR was turned on in the Packaging Settings > Description > Settings.

As soon as it asked what folder I should be packaging to, I noticed in the log it was already saying “LogSpawn:Warning: UWorld::DestroyActor: World has no context! World: fac, Actor: /Game/VirtualRealityBP/Maps/fac.fac:PersistentLevel.fac_C_1”

I’ve attached the log (before I chose a folder)

[link text][3]

Is it stuffing up because I dont have any meshes in “start”, or any player spawn in “fac”?

Thanks in advance.

Thanks Rudy, but does the VR template have any Parent / Child relationships?

Hi there Rudy,

I don’t think this answered my question because the VR template doesn’t have any Parent / Child relationships.

I have a quick question, if you delete your saved an intermediate folders before opening the project, do you still get the warning?

twistedpancreas · March 24, 2017, 9:49pm

Sorry Rudy, I don’t follow, which folders?

anonymous_user_e729f54e · April 5, 2017, 5:45pm

I have provided an example below of where to find these folders by default.

Example:

C:\Users\YourUserName\Documents\Unreal Projects\YourProjectName
