Dammit Dan!! why didnt you tell us we could do in 5 seconds what took us
hours to animate by hand! :P
nahh i know he was teahing us the principals of keyframes, timing and making us look at the graph
editor. still, i think i would have gotten a better mark had i known about this!
by adding active and passive nodes to polygons, then applying a gravity field to the active nodes, you can easilly create a bounce effect as shown here. what is recomended is that you only use this to generate a base effect. then bake the simulation into keyframes and go in and really make it your own (and what you actually want from the drop/bounce). This was very fun to learn and i urge others to play too! its like a better version of LBP!
