MHX Eye rotation problem

Should be fixed now. The problem was the roll angle of the eye bones, so you need to reimport the character before converting it to mhx .

Apparently my algorithm for calculating roll fails when the bone is almost perfectly aligned along the Y axis. Normally this is not a big deal, but it matters if you turn on the gaze bone, which is a Track To constraint with Z as the up axis. If the roll angle is wrong, Z does not point up and things go bad. You can see the Z axis as the small arrow on the eye bone’s custom shape.
