Hi,
4.25 fails to nativize any Blueprint Actors with replicated values. This is a disaster! I tried to open a Bug report, but I cannot find the bug that I filed :s
Anyone knows a workaround?

The below steps produce:

  1. Create Empty project.
  2. Create BluePrint Actor, name it BP_zzz.
  3. In BP_zzz, set Replication->Replicates to “True” (Checked).
  4. In BP_zzz, add Integer Variable, name it IntVal.
  5. In BP_zzz, set the IntVal->Replication to “Replicates”.
  6. In BP_zzz, inside the EventGraph, add EventBeginPlay then connect the execution line to Set the IntVal to “100”.
  7. Create and Open New Level called L_zzz.
  8. Drag-drop to add BP_zzz actor to the L_zzz.
  9. Open project settings->Maps & Modes->Set Editor Startup Map and Game Default Map to L_zzz.
  10. Open project Settings->Packaging->Set Build Configuration to “Shipping”, Full Rebuild and For Distribution to “True”,
  11. Open Project Settings->Packaging->Blueprint Nativization Method to “Inclusive”.
  12. Create New C++ Class from PlayerController, name it CppMyPlayerController.
  13. File->Package Project->Windows (64-bit).

Same problem.

Hi, this has been fixed for the 4.25.2 release, but you can quickly solve the issue by removing the private: on line 18 of Engine\Public\Net\NetPushModelHelpers.h

Thank you for the reply. Will this work even with the engine that was downloaded via the Epic client? (NOT GitHub->SourceCode->compile)
