This started as a simple test, could I get fast, interesting, animated clouds in Terragen. Rendered entirely in Terragen each shot took about a day to render with each frame coming in at 3 to 5 min. Pretty fast for Terragen! If I wanted to render with higher quality and detail settings it would still be possible without getting into silly timings.
The music, Movement Proposition, is from the free music site incompetech.com/, thankyou.
Hope you enjoy and thankyou for looking.
