I'm looking to start doing some animations and have a few questions that I hope someone can answer. These are questions I haven't been able to answer through google searches.

1. Is there an advantage in just keying the individual channels that are animated rather than the whole model?

2. What's the differences/advantages of smooth bind and rough bind. I've messed around with smooth bind, I don't really know anything about rough bind.

3. Is there a way to organise animations, ie. have an animation called "walk" that contains all the keyframes for that animation and that can be inserted into different places on the timeline. Or do you have to copy and paste particular sections of the animation each time.

4. What's the basic workflow for doing animation, I'm just looking for the steps, ie.
1. Bind skin
2. ........ etc...
