Damped Track
Damped Track is great for making one bone point toward another. I find placing a Damped Track constraint on the head is always a good idea; it’s a simple constraint but an exceptionally effective one. Figure 8.7 shows a Damped Track constraint in action:

Damped Track can be used for many different things, mostly when pointing at an object.
A surprise place you can use Damped Track is in a tail!
Model a simple tail and place a chain of bones in it. I used automatic weights just to keep it quick (great when it works).

Figure 8.8 – Damped Track in a tail setup
Each bone in the chain has a Damped Track constraint that targets the bone above it; it’s as simple as that, but grab the base bone and rotate it to see how impressively effective the result is! Note the Influence value; the stronger the value, the stronger the effect.
This lets you put the base...
