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"

ok, let me be clearer the problem is I added the plugin just to test and explore but now I don't want to use it. My project was completely built on blueprints and now I can't open because of the above said problem

From K4U's website:


While we are constantly searching for alternatives, in Unreal there is currently no way to package a project that includes a plugin without source code. This is a problem that Epic is also actively working on and is slated to be fixed in 2015. However, depending on your needs, it may not be necessary to package your plugin for deployment. This is particularly relevant to installations and exhibits, running your project from inside the editor as a new editor window or a standalone game, these both allow you resolution and full screen control equivalent to that of a packaged project.

If you absolutely need to package the project right now, there are two options:

Acquire a source code license from us. The cost varies depending on the scale of your project, so please contact us for more detail. For a fee, we can package your application for you. The cost varies depending on how much effort it requires, but generally ranges between $200 - $400 USD for projects that can be packaged directly from engine. For projects that require compilation from source, we recommend that you contact us to acquire a source license.

They're not clear if you simply need your project in c++; or if you need the Engine Source c++. I'm assuming that the plugin must be added in to the Engine's Source folder. If that's the case, you'll need to get the engine source code from GitHub; integrate the K4U plugin and compile.

I know the post says 2015; but it's looking like it hasn't been fixed yet.
