-How use Blender’s integrated bullet physics simulator, including:
-different collision bounds types (convex hull, mesh, etc)
-affect of scale
-baking simulation cache
-simulation duration
-simulation speed (to fix appearance of scale)
-converting simulation cache to keyframe
-use of the simply F-curves Blender add-on to simplify generated keyframes down to a useable amount.
