:)Patel, You ar a nice and helpfull man, and I am silly. But Blender ar also silly. I did what you told me and use Ctrl+A. I dont have any trubble to conect lattice to the object. No!
I got fed up, why the eyes jumping out of the head everytime I press Ctrl+P Lattice deform.
I made a new object and follow every step you told me.
Here is the steps I using. Se the new blendfile.
Made a new head. (every time I press Alt+R clear rotation.) This time I press Ctrl + A to.
Made one eye and eyelid Alt+R and Ctrl + A. Add Empty Alt+R. Constraints,Track to, select eye, typed Empty and select Empty arrow G and eye move perfect. Selected everything and Ctrl+A
Select everyting and made a dublett Shift + D move the eye to the other side. Alt+R and Ctrl +A.
I select only the eyelids and the head and press Ctrl+J.
I add a lattice. Select the head, eyes and with the shift button down I select the lattice and Lattice deform and the eyes jumping out from the head. WHY WHY,WHY???
I try the other way, made a constraint Track to, typed lattice before I work with the other things.
Still, eyes comming out from the head. Thats my silly problem.
I dont have any trubble, if I select everything ( the eyes to ) and press Ctrl+J. Lattice work perfect. But I cant move the eyes after that.
