View Full Version : Eye setup problem
08-12-2003, 06:29 PM
I've made a classic eye setup, for a head, no bones or so...
Head parent of 2 eyeballs and a Control Null
both eyeballs have follower applied Following Control Null (heading and pitch)
Controll Nul is targetting a NullCam
NullCam is child of Camera (so when I hit 0.0.0. eyes are looking at the camera)
It doesn't work !
If I move the camera, eyes are working nicely
If I move the timeline eyes are looking away (nonsense)

follower is a little bit strange sometimes, it doesnt work very well in IK chains. Try uncheck "After IK" in the follower panel.
Good Luck, Robert

This may be a silly question, but have you set a keyframe for your camera/target null before you move the timeline?
For eyes, I usually just put a separate weight map on each eye and set each eye bone to target my master eye null, which is a parent of a left eye null and a right eye null. That way you can move one control for both eyes, but you still maintain control over each eye individually in case you need to have them cross or spin like a crazy person in opposite directions. :p Easy to set up, and very reliable. :)

Thank you guys :)
Robsi, there is no bones...
TripleG, hahahaha, auto key is on, so answer is yes, there is keyframes :)
Your solution is what I use before, but I wanted to keep the eyes parallele.
Which I knew what's wrong with follower. Not the first time I have weird results with this...

All the best Robin

Howdy Robkoni :)
Yeah we have to stop, people would think things and then speak behind us...

Just a thought...I wonder if you wrote an actual expression instead of using Follower, if that would work? I know...sometimes Follower gets a little wonky. (That's the technical term for it, btw...) :D

I use targeting for eyes nowadays. Have you tried that?
For those who don't use this method:
model the eye in its own layer, centered at XYZ, facing Z+
in Layout, after you have converted skelegons to bones in the character mesh, and have recorded Pivot Rotations, parent the eye to the Head bone in the body mesh
position the eye, and create an eye targeting null
position the eye targeting null ahead of the head
select the eye and bring up the Motion Options panel (m key)
set the target for the eye to the eye target null
move the eye target null to animate eye
You can also add another null, positioned in the head, between the eyes, and call it eye target rotator
parent the eye target null to the eye target rotator
rotate the eye target rotator to animate the eyes, and move the eye target null along the Z axis to animate the eye's focal point
