Or, to put it more succinctly: elongated eyes :o. I've searched for methods of accomplishing this...the most popular with other 3d animation software seems to involve lattices...whereas Anim8or does not have this option (though that would be the icing on the cake if it did) the only other way to accomplish this would be to manually morph a pupil over the surface of the eye, or somehow move a texture in real-time. I'm in favor of moving the pupil...however, when my first run at this was disastrous as it mostly just 'vanished' while settling into its final position, or simply did not align properly with the contour. I've also tried attaching the pupil to the rest of the eye morphing the entire thing...but then the eye itself looked wonky, like it had an extra bit just sort of poking out from the rest. If anyone has an idea of how to better accomplish the effect, or anyway I can more effectively utilize current available options, I'd really appreciate some input.

"I'm in favor of moving the pupil...however, when my first run at this was disastrous as it mostly just 'vanished' while settling into its final position, or simply did not align properly with the contour."
 Try this method again?
 Perhaps add another morph to the pupil, which moves the pupil 'forward'.
 Then use a blend of both morphs.  One to the side, with a little bit of 'forward'.
 Use the graph editor to get it right.
 This method does work with odd, (elongated) eyes. The pupil is probably disappearing because of the front curve of the eyeball. ?.

The best advice I can offer is to follow reality and keep your eyeball spherical, using modelled eyelids to provide the elongated shape, unless you are going for a deliberately cartoonish, unrealistic appearance.  An example is Gollum from The Lord of the Rings, whose eyeballs are clearly large spheres behind carefully modelled eyelids to give a 'sneaky' or sly facial expression.  A spherical eyeball is easily animated by rotating about it's origin, and if you map one eyeball to the other in the orientation controller you need keyframe only the parent eyeball, allowing the child to follow.

Sorry I don't have an answer for you. Lattices are one feature I've wanted since the beginning, I got interested in 3d through watching Veggietales and naturally wanted to do their eyes, another example of this type of eye would be Mr. Potato head in Toy story... I wonder if, with scripting fully implemented into the scene, and figure editor, if lattices could be created with scripts... or maybe eyeball meta-objects, that would allow you to animate rotations as well as squish and stretch...

It's funny that the inherent geometry of a cartoon-ish character is more 'complex' in terms of visual dynamism than a realistic face because everything has to squash and stretch in 'unnatural' ways. I read that Terranim8or7101 can create animated textures, so I may check that out...it was also a good suggestion however, to model the eye-socket/eyelids to create the illusion that the eyes are elongated (like they seem to have done in 'Coraline') so I'll give that a try too. Thanks for the suggestion on syncing the eyes ENSONIQ5. though I haven't messed around much yet with controllers. BTW Johnar, I liked that little guy in your Morphing tutorial, the one with the Angelina Jolie lips.

For Coraline, elongated eyes would be much easier as well as it was done in stop-motion not CG
