Hi, PACCAP. I saw the source code and found UE4 doesn’t generate http chunk data for chunk0 by default. If you want you can change the source code.You can open CopyBuildStagingDirectory.Automation.cs which located in “Engine\Source\Programs\AutomationTool\Scipts”.Then jump to the line 1943, use if(ChunkID >= 0) instead of if(ChunkID != 0).Last, open the UE source solution with Visual Studio and build AutomationTool. enjoy~
