Hy...
I have an eye which is deformed by a lattice (like an egg). I want to have the pupil round all the time and to be close to the surface (imagine that the egg is my eye and the pupil is an round plane with enough parameters). There is any solution for that?
PS.: Till now i deformed just the eye ... and i didn't put the pupil inside the lattice that deform the eye. The pupil is parented to an locator which is sticked to the eye by an node of type PointOnSurfaceInfo (no matter how the surface is deformed, my locator remain on the same value on the surface (u,v)...).
