UKismetSystemLibrary::LogString

Description
Writes a string to the log without printing anything to screen. If bPrintToLog is true the message is visible in the Output Log at normal verbosity; otherwise it's logged at Verbose and generally won't show up.
Caveats & Gotchas
- • Marked DevelopmentOnly — calls compile out entirely in Shipping and Test builds, so don't rely on it for anything user-facing or for logging that must survive in production.
- • Unlike PrintString, this has no on-screen output and no WorldContextObject parameter — it only ever writes to the log.
