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"

"The following modules are missing or built with a different engine version" when create a C++ project

When I created a C++ project with basic code and starter content , only the Visual Studio opened , the editor didn't.Then I opened the just created project in the editor and it poped out "The following modules are missing or built with a different engine version: UE4Editor-xxx.dll"(xxx is the project name).

I can press "yes" button to rebuild the project and it can solve the problem.But it feels like a temp solution.The engine version is 4.12.5,so it's not because of the bug in 4.12.3.And it's probably not because of the anti-virus software if the rebuild was successful.

The engine is 4.12.5,built from source.The OS is Windows 7.And it only appear when I create a C++ project,blueprint project is fine.

Product Version: UE 4.12

I downloaded a compiled(binary) version of the 4.12.5 engine from the launcher , it can create C++ project correctly.

Hi Surtur,

When you are using an Engine that you have built from source code, a new code project must first be built in Visual Studio before it can be opened in the Editor. This is different from when creating a new code project using the binary Engine installed through the Launcher, which will automatically build the project and open it in both Visual Studio and the Editor.

Thank you for replying ,Tim.

So it's totally normal? Curious the two versions behave differently.

Yes, this is normal. There are a few small differences between the Engine when it is built from source code and when it is downloaded and installed through the Launcher, and this is one of them.
