Cube w shadow .veg shows how to create a rotating cube with transparency and a drop shadow. Track 9 is a simple color gradient background. Tracks 3-8 are the cube faces. The checkboard has transparency to allow you to see inside the box. Track 3 uses keyframed track z rotation to form the opening/closing box lid. Track 2 rotates the cube. Track 1 adds a 2D shadow to the cube.
