Http chunks not generated for chunk0

Hello, I am patching my android game based on previous release version. I have two chunks: chunk1 and another is the default 0. I both modified the assets in chunk1 and chunk0. I used the “Project Launcher” to make a patch. In the settings I selected “Create Http Chunk Install data”. After that I only got the chunk data of chunk1, it didnt generate chunk data of chunk0.I’m not sure it’s a bug or setting issues.

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~
