Non-spherical eye while keeping iris circular

2013-11-18 Thread Enrique Caballero
Hey everyone, Does anyone have any tips on how to rig a non spherical eye while maintaining a perfectly circular iris? I have done it in the past with starting with a spherical eye, using a lattice to deform it and then using blendshapes to counter the squashing effect on the iris. But this

I'm not a specialist in toon, but I would keep the Lattice on the Eye (the white deformed sphere) and make a separate Iris object that would be shrinkwarped on it. So that the Roundness of the Iris wouldn't be affected by the stretch of the global eye. Maybe a ClosestLocation in Ice would give

hey oliver, Thanks for the reply, that would work if the pupil was a separate piece of geometry and is exactly how i do it on other characters. Sorry I should have been more specific. Basically I'm trying to make the Pixar eyes. Where the iris is cut into the eyewhite, and actually goes

Hey Enrique! :) An idea could be to fit a NURBS sphere to the shape of your outer eye, then use it to constrain the deformers onto its surface, and finally slide those deformrs using UV coordinates. I did something like that a whle ago: http://vimeo.com/2466613 In this video the eyes are

If you have no textural detail in the eye and therefore can afford some discontinuity in the tension it's easy enough to achieve. Use one mesh for the deforming eye, a second one that's a proper sphere with the iris centered around the iris, bind it to the stretchy mesh from the iris out so the

thanks everyone, these are all really useful ideas. i will try them out and see which one i go with chris, i remember your eye rig from animal :) i was considering going a similar route as well! On Tue, Nov 19, 2013 at 9:49 AM, Raffaele Fragapane raffsxsil...@googlemail.com wrote: If you
