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"

Problem to create a C++ project

Hey guys, pls i need a fix quickly. I have windows 10 and visual studio 2017 and i'm not sure that i have sdk 8.1 but at VS installer i downloaded and installed windows sdk 8.1. I'm using unreal engine 4.15.2 or 4.16 preview3. when i try to create a c++ project i get this message.

The project could not be compiled. Would you like to open it in Visual Studio?

Just found the solution - It is searching for server to connect to, for Incredibuild

Add this to your build configuration file to disable the search:


Build configuration file is in: %APPDATA%\Unreal Engine\UnrealBuildTool

Press both Windows and R keys simultanously to

Execute "%APPDATA%\Unreal Engine\UnrealBuildTool"

It will open folder containing "BuildConfiguation.xml"

Modify "BuildConfiguration.xml" with any text editor (Sublime Text rocks) to be like following

 <?xml version="1.0" encoding="utf-8" ?>
 <Configuration xmlns="https://www.unrealengine.com/BuildConfiguration">
