QR Code
QR Code Generator is a simple plugin that let's you create QR Code in Unreal Engine. The plugin comes with simple functions where you can give the message to convert to QR Code.
Blueprint​
The functions can be called from anywhere in Blueprint or C++ since they are static.
C++​
To use in C++ you must first add the dependency to your Project's *.Build.cs file. Open it and add “QrCodeGenerator” to your .Build.cs file. It should typically look like this:
PublicDependencyModuleNames.AddRange(new string[] { "Core", "CoreUObject", "Engine", "InputCore", "OperatingSystemQRCode" });
Once the dependency is added you can simply call any of the static functions like this:
UOperatingSystemQrCodeGenerator::GenerateQrCodeTextureSimple(“Hello world”);
