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"

Best Practices for a shared Derived Data Cache?


I'm wondering if anyone here has developed some best practices for using a shared DDC. We often have multiple projects in the pipe, and I'm wondering if it would be better or not to split them up into multiple caches despite having some shared assets, or to keep everything in one big pool. I'm also wondering how often the DDC should be cleaned out, as ours is getting quite large and I'm not sure if the mechanisms in place are keeping unnecessary items out of it.

The only documentation I could find on this is pretty light and does note even explain what all the variables mean: https://docs.unrealengine.com/latest/INT/Engine/Basics/DerivedDataCache/index.html

For example, what are the following variables even supposed to do and how can we best take advantage of them? Clean=false, Flush=false, DeleteUnused=true, UnusedFileAge=19, FoldersToClean=-1

Any tips or tricks on this subject would be greatly appreciated!

Thanks, ​​​​​​​Bill
