Ouch!
Houston, we've got a problem!!!

In order to get this (IMO useful feature) to work I had to hard-code it into the figure file because simple dependencies wouldn't have worked.
The drawback is that it can't be controlled by an "on/off" dial like so many other features of SASHA.

To remove this you must create a NEW BASE FIGURE by editing the original

"runtimeData! KarinaSASHA-16SASHA-16 WM (BASE).cr2" (sic!)

Open the file with a text editor of your choice (I suggest "PoserFileEditor" by D3D)
Now search for these exact code lines:

linkParms    rEye:1
xrot
lEye:1
xrot
linkParms    rEye:1
yrot
lEye:1
yrot
linkParms    lEye:1
xrot
rEye:1
xrot
linkParms    lEye:1
yrot
rEye:1
yrot
 
 

(they may not be listed in that exact order, but they should...)

Now DELETE those EXACT 16 lines and save your .cr2 file under a different name, e.g.:
"runtimelibrariescharacterSASHA-16MY OWN PRESETSEyes decoupled.cr2"

Make sure to read the manual "9.1. Create your own custom Base Figure of SASHA-16" to better understand what you are doing! [cool]
Next time you need it you can simply load it from this location, with the eyes moving independently.

The true magic of Poser isn't just some buttons to press, but to be able to edit the source code of the files to achieve some incredible results!

Have fun!
