ok, im working with a character that has really narrow eyes and for the life of me I can't get the latice rig to deform his eyes properly.
So I've changed his eye style slightly and gotten it ok'd now what I have is a seperate pupil from the eye, which im going to have to restrain it to the actual eye so that it can properly rotate around it without leaving it..
I know this can be done, I saw it back in school, but for the Life of me I can't remember what the straints are.

Can Anyone help me out with this? I need to get this character pumped out and all thats left is fixing some minor stuff like the eyes. Thanks in advance.

why do you have a seperate pupil ?


Anyway just make sure your pivot point is the same place as the eye and link it to the eye, and then use a look at controller.

what app are you using.

Im using Maya, I probly should have mentioned that ^^;

I have a seperate Pupil because of the characters head style and general cartoon nature.

Unfortunatly its not as simple as making the pivot point equal to the rest of the eye, since the eye itself is enlongated and not a sphere.

I just tried out your suggestion but it doesn't work since its not a sphere the pupil simply enters the eye.

Thanks for the suggestion though any other ideas?

Try this, parent the eye (sphere at this point) and pupil (also sphere shaped) to a locator. Then scale the locator so that the sphere become the shape you want. Because this is a hierchy, when you rotate the sphere, (actually selecting the sphere and not the locator) it rotates but it's shap stays the same. Try it!

duno about maya, but in max we can link a kind of lattice to the sphere that deforms it, so when inside this "lattice" it gets shaped like the lattice. Like the egg shaped eye.

Yea maya can do the lattice deformer as well but the director for this shot doesn't want a lattice deformer in the rigging ^^;

Im gonna try your method right now gdimmrt thanks

gdimmrt your solution is great, doesn't quite work out properly just as I need a more dynamic shape then I can make by manipulating a locator but it sparked anouther idea and I think I've got it working now, although its limited mobility it works for what I need it for right now. Thanks alot

great you've got it to work!

erhmm why do the director care about the rigging ?

Its not mine to question why, it is but to do and die.


I have no idea ^^;

Scales in a hierachy are pretty bad to do, as transformtions are relative to there parent. Rotation and scale are directly linked and scale is the unit length of the 4x3 matrix. Position is another row and doesnt get affected by these problems.
