I’m following the tutorial for cartoon eyes at http://blenderprojects.com/calvin/CartoonEyes2/
Once I get to the point of adding a deformation lattice, when I stretch the lattice along z axis (vertical direction) the eyelids deform as expected, but the eyeball itself deforms in the wrong direction (outwards along the y axis).
Looks to me like the eyeball has a 90 degree rotation or something, and is the wrong way up. However, it needs top be this way up in order to make the iris point the right way.
What did I do wrong? How do I fix it?
Edit: Oh - I think I know what I did now, but I’m not sure that I quite understand it. The xyz of the lattice were wrong because I had my mouse on the wrong “view” when I made it. I should have added latice in the top (yx) view when I had instead added it in the front view (zx) so it ended up facing the wrong way.
I understand that shapes do face a different way depending whish view they are created in.
What I don’t understand is why this seems to affect the relationship the lattice has on the inner eyeball, but does not appear to matter for the eyelids (the eyelids always deform correctly, even as the eyeball misbehaves, no matter which view I use to add the lattice).
I would really like to understand this because I can see it causing a certain amount of “unpredictable” problems otherwise. Also, I would like to know the way of correcting this. I tried changing “Up” for a wrong lattice in Editing, but it did not correct the problem.
Does anyone know how to use lattices well?
