First of all had to do a title change to match my game intro screen. Here is an update of the bow with textures and it is also rigged now. I have been running tests of the animations in Unity as I have never setup animations to be taken into Unity. So far from the tests I recommend completely cleaning your scene up. Most of the rig and controls don't translate from Maya into Unity. It's best to bake the animation to the joints and then export that into Unity. I'll update as I run further tests.
Textures are looking pretty nice. The rig is setup so that the red control is used for the bend of the limbs and the yellow control is for the draw of the string giving more control of the appearance. The blue controller is the super mover for rig placement and scaling. Time to work on the textures and rig for the arm more to come...
