Inspired by a thread over in the Daz3d forums, AgeOfArmor put together a video of various tests and clips he made using Carrara’s particle engine. Some of the scenes are available on his website for any Carrara users interested in seeing how the particles were done.
Tutorial showing how AgeOfArmour’s GT40 vs Ball Bearing video was made. This video is not in depth but does give an overview of each stage of the process and how to work around a few physics issues, including using discrete keyframes to control gravity, and parenting the high-poly model to proxy parts.
