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"

Unreal Editor (4.21) doesent start on linux

Hello! When i try to start the Unreal Editor on Ubuntu 18.04.1 i get an error(in a STEAM window):"Plugin 'SteamVR' failed to load because module 'SteamVR' could not be loaded. There may be an operating system error or the module may not be properly setup.". The terminal gives me this warning:

LogCore: Warning: dlopen failed: /home/sebastian/Programme/UE4/4.21_SourceCode/UnrealEngine-4.21/Engine/Binaries/Linux/../../../Engine/Binaries/ThirdParty/OpenVR/OpenVRv1_0_16/linux64/libopenvr_api.so: undefined symbol: __dso_handle LogModuleManager: Warning: ModuleManager: Unable to load module '/home/sebastian/Programme/UE4/4.21_SourceCode/UnrealEngine-4.21/Engine/Plugins/Runtime/Steam/SteamVR/Binaries/Linux/libUE4Editor-SteamVR.so' because the file couldn't be loaded by the OS.

When i look into the folder i don't see the file. It is maybe missing. I hope you people can help me out with that.

Product Version: UE 4.21

You must have pulled the sources during an unlucky window when the (upcoming) 4.21.2 was broken. This is already fixed in 4.21 branch. Note that if you used the "release" branch (which is currently at 4.21.1) you would have not run into this problem :-)
