Summary
Somebody break out some trumpets and confetti! We've passed some major milestones in this chapter! You survived examining the default Blender interface without your head exploding, you learned how to transform objects in Object Mode, and you started the long journey of learning how to alter objects in Edit Mode. Armed with that knowledge we went ahead and changed a pre-existing object to our own specifications. (This is a huge accomplishment if you don't already know.) Finally, we exported the object for inclusion in our Unity mini-game.
You deserve some fun now! In the next exciting chapter, we return to Unity, lay some groundwork for the mini-game, and bring our turret to life with some motion, visual effects, and sound effects. Woohoo! Pew-pew-pew!
