True, but it only switches AA on or off for the defined material, it does not set any quality... By the way, if you set the quality slider of AA to 100% it does not mean that Vue will use all the "Subrays per pixel" you have defined in the settings. What I have undestood is, that it will use at least the minimum amount of Subrays per pixel, and then will use more untill it decides the quality of AA for that pixel has reached 100% or the maximum of "Subrays per pixel" has been used. What I am trying to say is: If you set a minimum of 12 and a maximum of 100, with a quality of 40%, the renderer might use the 12 "Subrays per pixel" for every pixel. Even though 2 might be enough for some areas (blue sky) while 40% will not be enough quality for other areas (hair).
