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"

Do I need to download the engine twice?

I downloaded everything as discribed in the video 'Downloading and Building UE4 Source' and now everything was working well.

Now I wanted to visit the markeplace to get some additional content and for that I needed to install the UnrealEngineLauncher. So I did. But immediately another download of 7GB (engine) + 3GB (content) started. So now it seems like I have the complete engine 2 times, one time in the github folder and another time in the UELauncher folder, although the size of the github folder is a lot bigger (about 15.7GB) than of the UELauncher folder (about 10GB still downloading the content). I just would like to know what is what. Which folder will be updated automatically and which one uses VS etc.?

thx a lot

If you installed originally from source the Launcher client isn't there, therefore it does need to download this content.

So now it seems like I have the complete engine 2 times, one time in the github folder and another time in the UELauncher folder, although the size of the github folder is a lot bigger (about 15.7GB) than of the UELauncher folder (about 10GB still downloading the content)

This seems to be the case if you want to compile from source, you effectively need two copies to run correctly, the good news is that updating the engine won't require you to download the entire 2 required + optional files from the repo but most likely just a new source ZIP under 100MB.

I just would like to know what is what. Which folder will be updated automatically and which one uses VS etc.?

The source you got from github allows you to build directly from source.

The one that you get through the client is updated automatically.

first of all thanks a lot for the quick response!

so if I want to add new classes in cpp that for example implemet a new AI or parts of it or some other function I need to start the editor from the github-folder and as long as I just want to use blueprints I can use the other one?

No, you can create new CPP's from within the editor, however the main engine/editor files will have been compiled into DLL's not allowing you access to their CPP content if there are any bugs.
