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"

Unreal 4.6.1 hangs on launch on yosemite

I've installed 4.6.1 on yosemite but when I launch it, it pops up a completely blank Unreal Project Browser and hangs there for well over 5 minutes. I have to do a force quit. I've uninstalled and cleared things out a few times to no avail.I've verified my installs. I'm at a loss on how to get this up and running. link text

Hi Spoogicus,

Are you still experiencing this issue? Try opening the editor directly from the application folder. If it opens, then it's a problem with the launcher only. If it still doesn't open it's a problem with the editor. Also, can you post more information on your system specs?

Thanks

One possibility is that there is a problem in a Module Manager test for a particular thread. At some point in the editor startup process, it hangs because the IsInGameThread condition is not TRUE. I made the following modification to the code and it started up fine, so I am not sure the test is actually needed on Mac OS X:

FModuleManager& FModuleManager::Get() { // FModuleManager is not thread-safe bool condition = true; condition = IsInGameThread(); // ensure(IsInGameThread()); // ensure(condition);

 // NOTE: The reason we initialize to NULL here is due to an issue with static initialization of variables with
 // constructors/destructors across DLL boundaries, where a function called from a statically constructed object
 // calls a function in another module (such as this function) that creates a static variable.  A crash can occur
 // because the static initialization of this DLL has not yet happened, and the CRT's list of static destructors
 // cannot be written to because it has not yet been initialized fully.    (@todo UE4 DLL)
 static FModuleManager* ModuleManager = NULL;
 
 if(condition == true) {

 if( ModuleManager == NULL )
 {
     ModuleManager = new FModuleManager();
 }

 return *ModuleManager;
 } else {
     return *ModuleManager;
 }

}
