Log to Console

Haven’t been able to find anything on this, is it possible to log to the client’s console?

Do you mean something like this?

Logs, Printing Messages To Yourself During Runtime

I do not believe any of those log to the ~ Console, am I wrong?

PlayerController::ClientMessage usually does this, and you can see how it passes through to ClientTeamMessage, and then (in the context of the local player controller) calls this:
CastChecked<ULocalPlayer>(Player)->ViewportClient->ViewportConsole->OutputText( SMod );

So ya, get a reference to the player controller, and call ClientMessage(TEXT(“Console message”));
