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"

Forgot this from the top of the crash reporter:

Assertion failed: (Index >= 0) & (Index < ArrayNum) [File:D:\Build\++UE4+Release-4.12+Compile\Sync\Engine\Source\Runtime\Core\Public\Containers\Array.h] [Line: 804] Array index out of bounds: 1 from an array of size 1

you might want to add a little more detail as when does this happens? is this random? is this when the game is playing? does this happens after you delete an Enumerator and are still trying to access to it? it looks like the engine is trying to access a deleted element that is still being used somewhere.

After installing a fresh version of the engine and on preview 5 this is happening... after launching the engine from the launcher it crashes at 0%. I was able to use the previous preview versions before preview 5 I believe. I did two things the first was importing fbx from blender with apex cloth from the nvidea clothing profile tool, and the second I believe I may have installed a piece of software (think it was a visual redistributable) when opening up a project could have been 4.12 preview 5 or a 4.11 project it was so routine I didn't really think about it until after the engine started crashing. I also deleted the project that is no longer opening unfortunately so I can't share it to see if anyone could determine what is happening from the project...

I would like to add that I have also completely removed (deleted the folders and files after uninstalling as well) the engine and reinstalled it and verified it several times, I even tried opening with just the engine selected and no other options but the same thing keeps happening.

This crash is related to a driver issue. Ensure that you have updated your graphics card drivers. If they are up-to-date, please provide your DxDiag so that I can take a look at any other potential hardware conflicts.

Thank you

link textI checked my drivers already as well, hope the dxdiag will reveal something!

Try updating your Display Link drivers. You can perform a google search for them and grab the latest. This crash has been known to be related to issues with Display Link drivers so this may resolve it.

avatar image sushichris Jun 02 '16 at 05:47 PM

downloaded and installed the drivers but to no avail :(

avatar image sushichris Jun 02 '16 at 05:55 PM

And to be honest I don't think I ever needed or had any reason to download that software.

avatar image Sean L ♦♦ STAFF Jun 02 '16 at 05:58 PM

Downloading that software has resolved the same issue for other users in the past, which is why I suggested it.

I've also seen another user experiencing this issue who states that "Disabling "OVRServiceLauncher.exe" in windows services fixes the crash".

Also, are you using any external plugins from the Marketplace or otherwise?

avatar image sushichris Jun 02 '16 at 06:13 PM

Ovrservice launcher might work, I will try when I get off work. I think the Oculus software did open up the first time it started crashing come to think of it!

avatar image sushichris Jun 02 '16 at 11:35 PM

That was it! I totally forgot that the rift turned on after that update... I just brushed it off like I had accidentally left it on or something.

Thanks!!! (I should have posted on here sooner lol)

So Sean Flint's source was right, I needed to disable OVRserviceLauncher.exe in windows services

"Disabling "OVRServiceLauncher.exe" in windows services fixes the crash".

Glad there's a workaround for launching the UE4 editor. Is there a bug report for this? Because of this I can't seem to test VR projects with the Oculus in the editor with 4.12. 4.11.2 works without issue.

avatar image sushichris Jun 04 '16 at 12:05 PM

After disabling the ovrservice and launching the 4.12 editor (as of today) rift turned on and the oculus launcher opened upon launching a 4.12 project and is working as expected. (maybe a restart helped?)

avatar image MagicBots Jul 03 '16 at 06:29 AM

Your sure you did nothing else besides restart? I still cannot get Oculus and any versions of 4.12 to work because of this crash. Killing the oculus launcher service and server in my task manager allows me to use 4.12, but oculus and 4.12 won't work together for me.

I had already posted my issue before finding this thread. Will link this thread to it. I've also included my dxdiag, msinfo32, and zipped crash ue4 crash log. If anyone has further info on how to fix this issue, and not just get around it by disabling oculus service please let me know.
