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"

This I could narrow the source down to this blueprint, I think. alt text

Imo, this error looks like UE not closing the PhysX library, it happen whatever the crash is, you will have more details in the log in the UE logs folder

Hello,

  • Could you please provide the logs from your project's Saved->Logs folder after the crash occurs?

  • Are you getting a Crash Reporter window? If so, can you please provide your Machine ID and ensure to hit Send & Close on the report?

Im affraight I don't have these logs anymore and the error is gone right now. But It had something to do with physics. I was attaching physical Objects to my pawn. I think you can close this one and as soon as I see this again, I know I need to attach the logs.

Hey weberl,

I'm going to mark this topic as resolved for tracking purposes. If the issue returns, feel free to reopen this thread and provide the logs.

Have a great day

Have you been able to reproduce this crash in a clean project?

Also, are you getting a crash reporter window? If so, please provide your Machine ID and ensure to hit Send & Close on the crash report.

Thank you

I am running the editor with this command parameters:

Is there a way to make it more verbose?

Just wanted to say I had this same crash/error but I noticed it only happens in levels containing BSP. I deleted all BSP and it's gone. Might help someone if they find this!
