I’m guessing you’re missing a module in your project. Wiki shows that this class is in the Blutility module. Add it and try building again.
YourProject.build.cs:
using UnrealBuildTool;
public class YourProject : ModuleRules {
public YourProject(ReadOnlyTargetRules Target) : base(Target) {
PCHUsage = PCHUsageMode.UseExplicitOrSharedPCHs;
// Add public modules here
PublicDependencyModuleNames.AddRange(new string[] {
"Core", "CoreUObject", "Engine"
});
}
}
