To get your eye working, right click (select) the eyeball.
In the panel that shows up, on the right there is your “TrackTo” contraint.
The TARGET:OB: field has nothing written in there! That’s probably because you spelt “Empty” wrong last time…
…write the word “Empty” into the box (no quotes though, and don’t forget the “p”)
If you get that right, you will find the iris (black dot) of your eyeball disappears.
To correct this, a little further down, where it says To: you can see that “Z” axis has been selected. Choose the “-Z” button instead.
…viola! The eye should now be working, following the empty whereever you move it.
I remember doing this tutorial ages ago. The hardest thing back then was trying to figure out the X, Y, Z, -X, -Y or -Z when I had no clue. Your is very nearly there. Stick with it. As confusing as these things can be, when you sleep on them, they eventually make lots of sense.
I dont know if you like my mouth, sphere and lattice to get the lips moving.
i need to practis how to join the lips to the face… If he smile, there is a big gap.
Your eyes are not working properly. There’s a bit of a mess happening.
First of all, you have confused the eyeballs with empties. You have named the eyeballs “Empty.001” and “Empty.003”. (You can see this when you click on each eyeball). Push N-key to bring up the properties dialogue and rename the left and right eyeball to “eyeball.L” and “eyeball.R”.
The real empties are hidden inside your head somewhere. There is a “cyclic dependency” issue here because on one hand you have the eyeball set to “track to” the empty, but on the other hand you have also set the empty to “track to” the eyeball!
Click each empty, and in the constraints panel, hit the little bold X to delete the TrackTo constraint. They don’t need them.
Then bring the empties from out of the head and put them in front of the character where he can see them.
Finally, you need to get the XYZ alignment correct so that it lines up with the empties. This is kind of a trial and error thing because it can depend on what way is “up” when the eyeballs are made. In your case, the eyes work when the To: field is set to -Z, with the Up: field being either X or Y (does not matter which).
Then, your eyes should be working. I’ve attached a modified version of your file to show the what it should then look like. When loading my file, hit “G” and wiggle your mouse around.
Worked first time for me, so let’s get it working for you. :eyebrowlift:
