When trying to build any game for Windows with the shipping configuration (I tested it with the Blueprint First Person Example), the build fails. Inside the UnrealBuildTool-[timestamp].log file, there is the following error:

Building UnrealHeaderTool...

Happens on both the promoted branch and on the master branch as of now.

Yea I’m also getting the same error in the same place but in 4.17. I hope this gets looked at soon. Builds fine from Editor in both DebugGame Editor and Development Editor but not in the UBT through the Command Prompt.

I got the same issue when i ■■■■ to package in Shipping mode. I’m working with the UE built from source from the release branch ( 4.17.1 at this time)

I’m getting this in 4.16.3 aswell recently

Temporary workaround

open:
c:\unrealengine\engine\source\runtime\renderer\private\postprocess\rendertargetpool.cpp

change the line to:

float ScaleX = DisplayExtent.X / ((float)MemoryStats.TotalColumnSize + 0.01f);
