Can't Keyboard Control Eye Gaze In Side Views

I normally stick with one behavior for eye gaze... although what you are doing should work too. If you want to stick with one Eye Gaze behavior, rename "left", "right", and "frontal" with "Left Profile", "Right Profile", and "Frontal Profile" so they get auto-tagged. Your left and right layers don't have the "Left Profile" and "Right Profile" tags on them. Frontal should have the "Frontal Profile" on it too.

To see if you have that step correct, expand say the "Eye Gaze" behavior and expand the "Views" section for the behavior in the properties panel. It should show "4" (the first is <root>, then stb/right, stb/left, stb/frontal). If you expand the Handles section just under it, you should wee "Head" with a count of 3 layers that it bound to (expand Head to see which layers it found). The Left Pupil, Right Eye, etc should all have the number 3 next to them too.

What happens is many behaviors understand profiles, so when you have a profile selected, the appropriate head and then eyes/pupils/range/etc are picked up for the current profile. No need to add multiple behaviors.

For you eyes, I think the left and right profiles are not set up quite right in the riggin hierarchy. Normally I would have "Left Eye" (where you have "Eyeset Left") and under that "Left Blink", "Left Pupil" and "Left Eyeball". The blink should be under the eye layer. Blink will hide all other siblings when a blink occurs. It seems to be latching on to .../left/head/eyeset left/eye left/eye left" (expand the views and handles sessions of the eye gaze and face behaviors). As a result, it did not pick up on the pupil range layer (the Eyeball layer).

I hope that makes sense

It appears that the walking controls are pre-empting the eye controls in this case, even without walking being functional. It would be useful to be able to assign those functions to different keys, but that's something for the tech guys.
