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"

Packaging for HTML5 fails with plugins


Packaging an empty project for HTML5 with some Plugins enabled fails. You might say it is the fault of third party programmers that causes the issue, which is true to some extent, as not all plugins cause the error. But on the other hand these programmers seem to be very competent and no one has a clue what is going on. Packaging for Windows works fine by the way.

So can someone from Epic maybe have a look into the issue?

The following Plugins are affected: (I have read in forums of other plugins being affected as well, but I didn't test them myself)

Building the engine from source resolves the problem. Anyway, it still would be nice if the binary version supported this.
