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"

DDC Cache issue

Hello guys,

I've recently updated to Unreal Engine version 4.18. I've solved all issues regarding the .uproject, .Target.cs and compiler issues. I can run and cook the game and it runs fine. The only problem I have encountered is with the DDC cache. Even after I open the project, I let it compile all shaders and detect all files the cache size still increases. I have a 2D project using Paper2D and after leaving the editor on for 1h the cache size is well over 10gb and increasing steadily. This also creates a high disk usage. This is not a problem on my main machine as I have a SSD and I didn't really notice it, but on my laptop it creates a 100% disk usage and I can't work at all.

I've tried the following things:

  • delete the Binaries / Intermediate / Saved folders from my projects

  • install / reinstall Unreal Engine and Unreal Launcher, including - delete all temp data from C:\Users\\AppData\Unreal* - delete all registry entries regarding unreal engine using regedit

  • changing the DDC cache location using the BaseEngine.ini config file

Below you have an excerpt from the Window Performance Monitor. It shows a lot of open file descriptor in the DDC cache location. A lot of the are also tagged with PHYSXPC, but I don't really know what that means.

I am running out of options, I don't really know how to solve this issue, any idea would be welcome. Is there something I am doing wrong? Are there any logs I could access that can help me?

Thanks, Andrei
