It works, but new detailed mode does not have all parameters, which were available in version 3.x.Does the option to switched to detailed mode not work for the custom faces?
I think that keep the old detailed mode in addition to two new will just give more control over face editing. Those who does not care, can use two new options, and those, who want more realistic face could use option 3 (old detailed mode) to fix problems that two new modes can't fix.
