That sounds awesome, I can’t wait! 
Been getting some help on the UE4 AnswerHub and have now got this; https://streamable.com/dskb
I had some issues getting the turret aiming to work since the mouse inputs inside A_Tracked_Vehicle are set to consume input, once I disabled that it worked like a charm in case anyone else runs into a similar issue. So now some final tweaks as I kinda messed the performance up and it doesn’t like going uphill at all anymore. And some speed and aiming restrictions to the turret. :rolleyes:
