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"

Cooker - LogDerivedDataCache:Error

At the end of the long cooking process I get the following error in the Output Log:

LogDerivedDataCache:Error: Could not save memory cache ?E:/UnrealProjects/xyz/DerivedDataCache/Boot.ddc?.

By that time it has already deleted all the cooked files again and I had to scroll up to find what went wrong.

So, anybody can help me find out what the problem actually is?

Hello ZeroComfort,

I have a couple questions to narrow down the issue you are experiencing.

  1. Have you deleted your Saved & Intermediate folders?

  2. Could you post the full log for your packaging?

Hi Thomas, thanks for replying!

I haven't deleted those folders. And the Error I've posted seems to be the only blocking one in the entire log. Though I would have posted it if I hadn't worked it out already:

Now, I've managed to fix this issue myself after digging around, because I thought the DerivedDataCache location was a bit weird with those question marks surrounding it. After looking at this I figured that it might fail because the quotes were replaced with question marks (for some weird unknown reason), so I replaced them with quotes and now it seems to cook just fine.
