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"

Unreal crashes on opening level

Crashes as soon as I open the level I have been working on, completely out of the blue. Worked fine the other day and now it won't open :(

This is the bug report :

Hi Denjino,

Does this occur on a blank project with no additional content? Additionally, can you post your logs here so we can have a look?

Please note that these logs contain your email address. If you are not comfortable posting them here, please feel free to message them to me on the forums at forums.unrealengine.com.

It occurs on a project that has a fair bit of content in it.

I opened the project on the new preview of 4.5 and it works fine. I think for now i'll just go with it and post back if it occurs again.

Thanks of the help.
