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"

Ubuntu 18 Cannot find compatible Vulkan driver (ICD)

I followed the instructions on https://docs.unrealengine.com/en-us/Platforms/Linux/BeginnerLinuxDeveloper/SettingUpAnUnrealWorkflow

When I run Engine/Binaries/Linux/UE4Editor, I get the following error Cannot find compatible Vulkan driver (ICD). I did however install Vulkan SDK. I am using Intel Corporation Skylake GT2 [HD Graphics 520] (rev 07).

Try running UE4Editor with the -opengl4 switch. I had the same problem and that worked for me.

How do you do that?

Go in your build folder (ex Build/Linux) and run the command ./UE4Editor -opengl4. That worked for me too!
