I did warn folks that render times could be very long, perhaps it should have been in very bold print. The best solution to avoiding the “nightmare” is to render when you are sleeping. Overnight renders are not unusual in 3D apps as well.
When I rendered without motion blur my render time was under two hours, with motion blur it was 11 hours. The lights do increase renders as well. I was also rendering at 360 by 240 full resolution for the tutorial.
I am planning to revisit strategies for improving renders etc… I have some thoughts on it and will release them when I can test them out; but my initial goal was to demonstrate that it could be done in AE not that it is the most efficient option.
