When I preview the render of my shot the skateboard/skateboard texture is transparent when it should be solid. The second picture is what it should(?) look like. As to how I set the scene up; I motion tracked the clip and used a floor that was generated by that. I imported the skateboard model. Using cycles render I made a new material and set the color to image texture and used the texture image that came with the model. After following a few tutorials a set up the three nodes belows. Any help is greatly appreciated.
