pose to pose pt 1
pose to pose pt 2
As i said in my first post there are a number of the 3D tutorials for the different principles; here are links to tutorials on 'pose to pose' and 'straight ahead' techniques.
Pose to pose tutorials showing a better planned and structured technique using key frames, whereas the straight ahead method is spontaneous, making up the animation as you go. Neither method is shown to be better than the other, they both have different strengths and weaknesses.
