Test flipbooks & Renders

In order to prevent the smoke from rising too quickly, I reduced the uniform force, however, the side to side motion was still a little fast. To solve this a drag was used to slow the smoke down. The sine function of the vorticle's transform node was also further tweaked to get this movement.

Finally I needed to render the smoke without the dragon, however the depth of the smoke could not bet seen if the dragon was just composited on top or below the smoke. A matte of the dragon would have to be rendered with the smoke to achieve the desired effect. The matte shader did not work out in this case, giving an undesirable alpha. In order to generate an image with the dragon completely black, I applied a color node with a constant black on to the dragon. I could then shuffle the red channel to the alpha in Nuke.
