Hey this looks real interesting. I'm glad to see this old vehicle back in action. Thanks for the props, Leon. As he said, we had our own version of it in development but unfortunately it didn't come to pass. It looks like you're trying to teach the old 'dog some new tricks.
As for the turret problem, that reminds me of a vaguely similar one I had with a program I was writing back in my college days. I was trying to write code for an incremend/decrement control in VisualBASIC v4.0 (that'll tell ya how old I am). When I ran the program and clicked the up arrow, the values in the display box went down instead of up. Now if I recall, it turned out I had to reverse the polarity on the equation for the control in order for it to work properly. It sounds counterintuitive, but it worked there, and it might for you. If you need some sounds I can help you out there. That's my forte.
I used vb 4.0 too - I started a course in programming back in 1995 (learning how to covert binary > hex > denary >octal was one of my first classes ) which I sadly bailed on to go on to do art instead. I used to make games back in the day on a Dell 286 with GWBasic (Never really liked Qbasic/QuickBasic for its lack of line numbers! ).
I remember the time I was in the library at the college (in the days before all machines were even networked, let alone globally hooked up to the 'net ) showing a mate some games, finding a bug in one and pulling up the code, and the library assistant dashing over and telling me off after seeing me scrolling through the code (presumably thinking I was hacking the machine.).
I think what I'll do with the pivot issue ( Wormbo gave me a hint in the coding forum that UnrealEngine flips its Y-axis for some reason ) is simply change the headlight corona (already done) and code the turret to invert its rotation ( not yet figured this part out, as I may need to subclass higher up the tree to make an inverted version).
Some sounds if you're up for it, would be very gladly received, I had a quick look around for some nice v8/truck/humvee sounds for the engine, but couldn't find a full set of start-up/shut-down/idle sounds, also a couple of new horns.
