Environment Animation in Blender 2.5
This tutorial goes through techniques to rig and animate props and environment objects that you need full control over. Simulations have their uses but in this example, a video game sequence where the player causes a piece of debris to form a bridge, the placement must be the same every time. This can be achieved manually with keyframe animation. Here is a .zip of containing two blend files from the start and outcome of the tutorial.
