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"

just downloaded the 4.7.6 version, and repeat my operation, this time the "build" is ok with default level. It seems it's a bug of 4.8!

Anyone answering the light build stall issue or are we just going to ignore it?

Hi all,

We've assigned a member of our staff to look into this issue for you. Please copy and paste the information from the Crash Reporter window when this crash occurs, and zip/attach the log from the project's Saved\Logs folder. Thanks!

Hey flyisland,

I attempted to reproduce the crash you are reporting in the binary release of 4.8.2, but was unable to do so. Are you using a source build or the binary release of the engine?

Would you mind testing this issue in a 4.8.2 build to see if the crash still occurs? Let me know if you have any other questions or need additional assistance.

Thank you,

Andrew Hurley

Hi all, just tried 4.8.2, same issue!

But I tried 4.8.1 on my another laptop (Lenovo T410 with Win7), the building is successful.

I guess this issue is related to the display card.

Hey flyisland,

If you are getting the correct results with the same project on a different computer, we can assume it is your other computers hardware or software that is causing the issue. I would suggest updating your drivers.
