Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Web browser ui widget doesn't run

I have been playing around with the web browser widget and while it works in the editor testing, it prevents any project it is in from building/launching.

My reproducible steps:

  • create a new project from blueprint template (i.e 3rd person template)

  • add the web browser plugin from the plugins menu

  • create a blueprint ui widget that only has a web browser box in it

  • have gamemode add the ui widget to the viewport

  • press launch button (or build for windows), it will build but open to a black screen and a fatal error prompt.

I understand it is experimental but it should be build able I would think.

Can anyone confirm that they can actually run with this widget? What might I be doing wrong?

Thanks Rudy, I appreciate you looking into it. It is good to know you see it as well. I was contemplating reinstalling ue4 to try to fix some setup/config problem.

I can only hope it is something that has a simple fix, and that it can make it into a future version. Given how useful it is to see any webpage, and how nice the widget is to use in blueprints, it would be a shame for it never to be used by any developer due to this build problem

Hi Rudy any updates on this issue? I can't run my build either. Didn't test this in 4.9 yet though.

Regards

I've just come across this issue too in 4.9.2. Had a quick look at the release notes for 4.10 but I couldn't see any mention of a fix yet, any news?

Hi Rudy, Any updates on the issue (UE-19350) regarding Web Browser UI widget failure when packaging project?

Kind regards SBK3Dteam

Hi Rudy, Thanks for quick reply. I checked your link, sorry if it's obvious but is the status of that link that the issue cannot be reproduced? I saw Tim Hobson's answer on the community ref with a possible fix with 4.11?

avatar image Rudy Q ♦♦ STAFF Apr 21 '17 at 02:58 PM

Cannot reproduce means that the issue could not be reproduced any longer in the latest build (4.11 at the time) with the reproduction steps provided in the report. Meaning that the issue was no longer occurring. I hope that this information helps.

Make it a great day

Thanks for your explaination Rudy. In 4.14.3 I tried these steps:

  1. Create a project with FP-Shooter template.

  2. Enabled the Web Browser Plugin

  3. Tried packaging the project to Win64 platform

Got this error message (last three lines):

*UATHelper: Packaging (Windows (64-bit)): Program.Main: AutomationTool exiting with ExitCode=5 (5) UATHelper: Packaging (Windows (64-bit)): BUILD FAILED

PackagingResults:Error: Error Unknown Error*

If I tried add the Web Browser to a widget with a valid URL between steps 2.-3. I get the same error result.

As soon as I disable the plugin the packaging works fine.

Many thanks

I tried these steps in the FPS template in for 4.14.3 and was unable to reproduce the error that you are seeing. Are you using the binary build of the engine or are you using source?

avatar image SBK3d Apr 26 '17 at 02:50 PM

Thanks for your reply Rudy. Sorry I am pretty new to the build (package) process. Where do you choose option for binary or source? Where you able to package project with no errors using Web Browser plugin in 4.13.3 depending on binary or source?

Many thanks

avatar image Rudy Q ♦♦ STAFF Apr 26 '17 at 03:26 PM

If you are using the launcher to create your project, you are using the binary version of the engine. This (the binary version) is what I used when testing. The question was used to narrow down further any differences in my test case versus the one provided. As stated above I was able to package without any issues. Could you clear your output log, package again, and then provide the complete output log after it fails to build so that I could take a closer look?

avatar image SBK3d Apr 26 '17 at 05:26 PM

Thanks for getting back. I tried produce previous explained steps and do a project launch. I had the "base" settings: Variant: WindowsNoEditor Config: Development Data Build: On the fly & By the Book

I am quite unsure about advanced settings tab. The following line is withdraw from the log output file:

Program.Main: ERROR: AutomationTool terminated with exception: AutomationTool.AutomationException: Stage Failed. Missing receipt 'MyProject.target'. Check that this target has been built. link text

Could you take a look at the post that I have linked below? The user on the thread provided was able to resolve the error that you are receiving.

Hi, tried to have a look and tried:

  1. Add this line to the command line of output log in FP-Shoot template:

runuat.bat BuildTarget -TargetPlatforms=Win64 -Config=Development -Project=C:\Users\Asus\Documents\Unreal_Projects\MyProject\MyProject.uproject -Target=Game

  1. Do a project launch to Win64 WindowsNoEditor

Got the attached files error messagelink text

I have a quick test for you. Could you try packaging the project via File > Package Project > Windows > Windows (64 bit) (example below)? After this you can try packaging via the project launcher. Packaging using the method above should clear up the error that you are receiving in the project launcher.

Example:

avatar image SBK3d May 02 '17 at 08:20 PM

Thanks for checking. Just FYI below steps are with Web Browser Plugin enabled. When I do your test above via File > Package Project > Windows > Windows (64 bit)

I get this error message, last three lines:

UATHelper: Packaging (Windows (64-bit)): Program.Main: AutomationTool exiting with ExitCode=5 (5) UATHelper: Packaging (Windows (64-bit)): BUILD FAILED PackagingResults:Error: Error Unknown Error

Then I tried step 2 via project launcher but unfortunately I get the same error message as the projectlauncher.log above. Am I supposted to type in the text line in output log before executing project launcher?:

runuat.bat BuildTarget -TargetPlatforms=Win64 -Config=Development -Project=C:\Users\Asus\Documents\Unreal_Projects\MyProject\MyProject.uproject -Target=Game

avatar image Rudy Q ♦♦ STAFF May 03 '17 at 09:16 PM

When getting "Error unknown error" you will need to look higher up in the logs for the error that you are experiencing. You can type "Error" into the search field for the output log and this will narrow down the possible issue that you are having. Could you do this and provide the errors that you are given.

The line at the end of your last comment was not needed for the last test.

avatar image SBK3d May 04 '17 at 06:34 PM

Thanks for your quick reply! I followed your tip and was able to narrow down the error message which stated that:

Windows SDK v8.1 must be installed in order to build this target.

So I downloaded and installed the SDK and Modified Visual Studio 2015 to update with "Common Tools For Visual C++ 2015" and that did the trick in my case after enable the Web Widget plugin and be able to package the project.

Thanks again for your support!

Just found out that \Engine\Binaries\ThirdParty\CEF3 is missing from the packaged project, I copied the folder into my packaged project ( \WindowsNoEditor\Engine\Binaries\ThirdParty ) and the web browser worked.

Hope that helps,

Rob

This doesn't work on an unpackaged/built project - and same crashing that is exhibited above (4.10 version)

have tried in a blank C++ and blueprint only project and still crashing.

Is there somewhere to copy the CEF3 folder to for an unbuilt project?

avatar image Rudy Q ♦♦ STAFF Nov 30 '15 at 02:36 PM

Hello walldiv,

The above issue deals specifically with the packaging issue that is being experienced. If you are experiencing a crash within the editor this may be a separate issue. Could you create a new thread (for tracking purposes) with answers to the questions below and provide a link in a reply to this thread? After that I will be able to assist you further.

Quick questions:

  1. Can you reproduce this issue in a clean project?

  2. If so, could you provide a detailed set of steps to reproduce this issue on our end?

  3. Could you provide screen shots of any blueprints/widgets that may be involved?

I tried to package my project in MAC OS X EI Capitan.

In Project, I had only enable WebBrowser Widget from Plugin and set build configuration to 'Shipping'. But failed to package.

I also tried 'Development', But got same errors.

Hello L34D3R,

EDIT: Removed answer due to incorrect information.

After looking into the issue further I was able to find that this issue has not yet been resolved.

Make it a great day

I have the same issue, crashing on shipping packaged build.

avatar image ooParanoia Jan 17 '16 at 02:06 PM

Thanks a lot.

Worked for me. Though just tested for 64bit dev build.

 Just FYI, I used v. 4.14.3 and  4.15.1 to try package.

Also got the tip to use setting "Compressed coocked package"?
