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"

.pdb file in packaged game since 4.20

In 4.19 and before, in the file "Engine\Binaries\Win64" of my packaged game, there would only be a .exe file (Blueprints only project) but since 4.20, there is an additional .pdb file included. Deleting the file still allows the game to work properly and drastically reduces the file size .

Is this file actually needed? If not, how do I remove it from the build?

Product Version: UE 4.20

The pdb files suggest that it is forced into building /DEBUG somehow even when set to Shipping (release) mode. And I can confirm the files are there and causing size issues. My settings are set to not include debug data. Can we get some help on this?

(oh and yes you can search .pdb and delete them without the game being bricked, still needs to be fixed)

I don't know if you did it before, but I just submitted a bug about this problem (that I just noticed as well) through https://epicsupport.force.com/unrealengine/s/

Don't forget to submit the bug there in the future, otherwise I doubt it will be noticed.

There are .pdb files also in Engine/Binaries/ThirdParty/PhysX3/Win64/VS2015 -- I'm assuming they are not needed either? The game launches fine but I don't have a lot going on to determine if everything PhysX related works.
