cartoon eye rig qeury

[gigsywigsy]

hello, is there any way i can rig an object so it follows the surface of another object when moved. For example iv made a cartoon eye with a pupil and i need the pupil to move across the surface of the eye without the pupil going through the white eye mesh,
any help would be great

a better way to do this would be to make spherical eyes as usual... set up your eye rig however you normally do it for spherical eyes... then add a lattice on top of that that deforms the eye and pupil together. you can make the eye entirely flat, conformed to a surface, etc... rotating the eye will still work wonderfully. but you'll get the effect you're looking for.

interesting idea, cheers il give it a try

just tried, works brilliantly , thank you very much i was getting so confused how to go about it, is amazing how people work ways around problems within 3d,

nice one

ooo iv encounterred a problem, when i rotate the eye inside the lattice it does this (seen in the pic) it has only started doing that, not sure why

[Zerflag]

it has to do with the falloff of the lattice's effect given the bounding box. just up the falloff and you should be good to go.
