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"

How to load level(and it's assets) from an external file in a packaged build?

I am currently working on a project where I am required to create a "Master" Game which is supposed to open levels through a UDP message from another application. These levels and their assets will be dropped into the Content folder in .pak files after I have packaged the game. Since I don't know much about packaging and deployment, I want to know if it is at all possible to load levels externally from a .pak or .umap file?

P.S. I have already tried putting the .umap file inside the Content folder, but loading that level only works in the editor. If I try to open it through a packaged game it either gives me an error of "Cannot find file" or just restarts the current level.

Product Version: UE 4.16

Well, what I finally ended up doing was a bit "unethical", I'd say. I created a new project with the same project name, project settings and engine version and then created a new level there. After compiling and cooking the content, I used UnrealPak to package only what I needed and then dropped that .pak file into my "master" game's project folder. Upon launch, it picks up the content and I can open the maps through command line. I just needed to make sure there no clashes in files paths in any of the additional .pak files.
