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"

4.10 Previews keeps rebuilding DDC at project load

I converted a BP-project from 4.9 to 4.10 Preview (Launcher Version) and it keeps rebuilding the DerivedDataCache at project load. At first, i thought it was because I changed the path for "Local" in BaseEngine.ini under "InstalledDerivedDataBackendGraph" but I reverted it to: "Path="%ENGINEVERSIONAGNOSTICUSERDIR%DerivedDataCache"" to no avail.

I also got these warning messages A LOT! :

LogDerivedDataCache:Warning: FDerivedDataBackendAsyncPutWrapper:

Put failed, keeping in memory copy TEXTURE_814DCC3DC72143F49509781513CB9855_BC5_12A6CAD142B78D48DCBD3887C091040A___82DEE4C828A98509F49C65367156EDED08EC7C76.

Edit: I also get this warning messages in a fresh BP-Project (FP-Template) for every texture when building shaders

Product Version: UE 4.10 Preview

Hello -

Can you confirm a few things for me? Can you reproduce this with any of the templates or Learn Tab Projects like Reflections etc or is this only happening in one project for you? Also are you opening a copy of said project or converting in place, or right clicking and switching engine versions?

Thank You

Eric Ketchum

Hey Eric, Thank you for taking the time! You can mark this report as Answered/Done. I reverted the wrong BaseEngine.ini and it is fine, now. Feel stupid about this as I really try not to report Bugs too fast and always try to make sure the mistake is not on my end. And i was skeptical about the DDC from the beginning because I messed around with it and no one else had problems! Now it turns out, I reverted the wrong BaseEngine.ini. Thank you very much for your time!
