Yes, another brain turn. Now with Eyes. Add a tail and EyeBrain can be animated.
I am doing this in Lightwave since that's what I'm teaching at Montclair State. Have been struggling a bit with the IK system, their base system has some quirks*. There is another system, called IK-Booster, which seems to be easier to manage. Downside is that it is quite different from what I know from other 3D software packages. So it is not something I am going to encourage my students to use, since that knowledge will not be very useful unless they stick to LightWave.
* It seems the IK gets evaluated before any "point at target" constraints, which makes having eyes look at a target a bit harder. Especially if you have these muscles on the side that need to move with it. Finally got rid of all the bones in the muscles and faked it...
