I amworking on a animation that shows the mode of action of a certain drug. The animation follows a the journey of a capsule down into the stomach. The capsule then breaks apart and releases loads of granules.Any ideas how to easily realistically animate loads of granules along similar paths at varying speeds, without making things get very complicated in the keyframer. I have already tried with 7 clones of the same object…but this means things get overly complicated.
