I want to paint one eye on my model but when I activate symmetry/radial it is not focusing only on the eye. I have the eye selected in subtools. How can I have symmetry just on the one eye?
Hide everything but the eye.
Transform-sPivot. That will center your model.
Turn on your symmetry as you want.
Once done go to transform-cPivot that will put your mesh back in place.
