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"

Packaged Win64 Shipping Build Crashes on Launch with Oculus Online Subsystem

Hello, I am currently having issues with launching a packaged game using the Oculus online subsystem with version 4.13.0 (Preview 1) of the engine. After loading up a blank project and adding in the assumed proper setting to the DefaultEngine.ini file as follows:

[/Script/Engine.GameEngine] +NetDriverDefinitions=(DefName="GameNetDriver",DriverClassName="OnlineSubsystemOculus.OculusNetDriver",DriverClassNameFallback="OnlineSubsystemUtils.IpNetDriver")

[OnlineSubsystemOculus] bEnabled=true OculusAppId="App ID here"

[/Script/OculusSubsystemSteam.OculusNetDriver] NetConnectionClassName="OnlineSubsystemOculus.OculusNetConnection"

The game will package in shipping mode, but the game will crash upon launch with this (https://puu.sh/qu4Ku/f787cb4f93.zip) error log. Screenshot of crash: https://puu.sh/qu6P9/6998ff94ef.png However, when packaging in development mode the game launches properly. It appears that enabling the Oculus online subsystem plugin is the reason why the game is crashing upon exporting it. This is also a blueprints project.

Thank you for the help,


Product Version: UE 4.13 Preview

On further testing, uploading the project to the Oculus store and running it as a test build does not fix the crashing.

I have a few questions:

  • Could you try packaging it for Development and see if you get the same crash? If you do, please provide your Machine ID and ensure to hit Send & Close on the report.

  • Also, after the crash occurs, provide the logs from the Saved->Logs folder.

Hi Sean, The error does not exist when I package it for Development. Only when I package it for shipping. Machine ID: 2391079543D984A9912964AE5A93569A

With the crash in shipping, we don't have a Saved->Logs folder. All we have are files that we have provided in https://puu.sh/qu4Ku/f787cb4f93.zip

I just tried with empty 3rd person shooter project, only difference is the Online Subsystem: Oculus plugin is enabled. Runs fine in Editor, fails to launch on Shipping build.

Would you happen to know if this crash is in 4.12.5? We are currently using Oculus SDK 1.9?

Hey BasswingLeader,

What steps are you taking to get the crash to reproduce on 4.12? That way I can go ahead and test it to see if it's occurring there as well, but the Oculus Subsystem was moved into a plugin for 4.13, so it functions a bit differently which is why I am asking what process you're using when getting this issue in 4.12.
