I would like to generate an animation representing a coin spinning around the vertical axis.
With 3D interpolation I can simply do this.
I'd like to add a "second side" on my coin. Then, my idea is to generate a second rotation with another picture (in fact it is inside a clip) and then use "masks" to show one side of my coin and hide the other side.
The problem is that the mask does not maks anything but generate very strange behavour: my coin becomes epileptic
What is the good way to do this ?
