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"

simplygon in custom built engine 4.13

Our team use a custom built unreal4.13. And we are trying to add simplygon to our engine.

The simplygon plugins worked on official unreal4.13(download in launcher). But failed on our custom engine.

I know that 4.14 has built-in auto mesh reduction. But it is not easy for us to update engine version.

What should I do to make it work on 4.13? Or How can I copy the auto mesh reduction from 4.14 to 4.13?

Product Version: UE 4.13

found solution

change "CheckModuleCompatibility" function in Source/Runtime/Core/Private\Modules\ModuleManager.cpp

 bool FModuleManager::CheckModuleCompatibility(const TCHAR* Filename)
 {
     int32 ModuleApiVersion = FPlatformProcess::GetDllApiVersion(Filename);
     int32 CompiledInApiVersion = MODULE_API_VERSION;
     return true;
     if (ModuleApiVersion != CompiledInApiVersion)
     {
         if (wcscmp(Filename, TEXT("UE4Editor-SimplygonMeshReduction.dll")) == 0
             || wcscmp(Filename, TEXT("UE4Editor-SimplygonSwarm.dll")) == 0)
         {
             return true;
         }
         UE_LOG(LogModuleManager, Warning, TEXT("Found module file %s (API version %d), but it was incompatible with the current engine API version (%d). This is likely a stale module that must be recompiled."), Filename, ModuleApiVersion, CompiledInApiVersion);
         return false;
     }
 
     return true;
 }
