When I posted my Gun Turret Animation a while back I was unhappy with the actual guns, I thought there was way too many lasers in the shot. so I made some new guns that I was going to attach to the turret, anyway this is where I got up to work wise with them, and eventually I plan to attach them to the turret and re-texture the scene etc... I decided to go with guns that recoil as I always loved the guns on the AT-AT in The Empire Strikes Back and how they fire, one then the other.
Here the animation test I did at the time of building the turret Gun Barrel test
It's just a test to see how the recoil will work.
Also here's the link back to my original animation of the turret Gun Turret Animation
