Engine crash in Blueprint project

Dusaral · October 28, 2015, 3:19pm

Hi guys,

Several times, the engine crashes, almost each times I’m trying a modification on my Blueprints system. It’s based on the TwinStick Shooter tutorial provided by epic, so there is a C++ code based. During the tutorial it NEVER ever crashed. Then, I did my modifications to create my personal project, based only on Blueprint. Since a week, it always crashes at a random moment. I tried the project on two different computers, the issue is still there, and it’s seriously killin me.

Here is the diag :

Unknown exception - code 00000001 (first/second chance not available)

Please guys, if there is any solution for this type crash, tell me, because it is avoiding me working …
Thx, you’re the best !

Hello Dusaral,

Could you provide your DxDiag?
Could you provide your logs?
What were the steps that you took before the crash occurred?
If you know the steps, can you reproduce the crash in a new project?

Thank you.

Hi Sean,
Sorry for the delay between your and my answer.

I can’t provide you my dxdiag right now, it’s the office computer so … I 'll do that with my personal computer.

Here his the diagnostic I got from the crash, I hope that’s what you’re looking for : link text

I can’t insert he file in the comment for a wierd reason sorry …

I still can’t give you the steps, because this is random. Here, the title crashes after I compiled my main blueprint, which is my character blueprint.

Thx

Hi Dusaral,

Zip up the logs from your Project’s Saved\Logs folder, and then you should be able to attach that. Next time the crash happens, copy the information in the Crash Reporter window, including the Machine ID, and paste that information here. Ensure that you hit send when the Crash Reporter window appears.

Hi Sean,

So here is the zip of the logs and the dxdiag. Next time I got the crash (from my personal computer, where the dxdiag and the logs comes from), I will paste it here

And here is the new callstack I got from the latest crash (in a zip text file)

Could you zip up the project and provide a link to Dropbox or Google Drive so that I could look at the cause of the crash?
What steps can I take inside of your project to get the crash to appear, or is it always at a random time?
Have you tried to update the project to the 4.10 Preview and see if the crash is still occurring?

Hello Sean,

Actually, by moving to the version 4.10 preview 4, the crash is not occuring anymore :o !
It may comes from the fact that I was using visual sudio community 2013, and the 4.10 engine version is only working with the visual studio community 2015 version.
