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"

Unable to start dedicated server on Linux

I'm having an issue starting a dedicated server under Linux. I'm using the editor with the options: "-server -log -map Example_Map". However, the game crashes shortly after launch with a shader error. Here is the portion of the log where things go bad:

 Shader type was loaded after engine init, use ELoadingPhase::PostConfigInit on your module to cause it to load earlier.

I'm able to run the Editor and the Client just fine. The server is a no-go.

1 answer: sort voted first

For the record, this is what was found while discussing this on IRC: SlateRHIRenderer module being loaded as part of FProjectManager::LoadModulesForProject phase (that is, too late). Why exactly this happens is unclear - the module is indeed a dependency of one of project's modules, but it doesn't seem to be loaded on Windows (not at that stage at least).
