I have a tank driving around my map, but whenever it turns, it goes backwards, how do I fix it?

When I turned off turning, it moved fine

If I had to guess, its because the tank prop isn't rotated properly relative to the tracktrain. Source thinks of the default rotation for objects as facing to the west (i.e. to the right in the top viewport). Rotate your tank to face that direction and then it should always face the direction it moves in.

I sent you the vmf on the other thread, so you can see for yourself
