I think,,, if sensitivitiy is old name of subDivision level,,(value,,),,
then you created sphere or cube,, and change the parameter ,, (yes you can change 0 to 2 ,,I think,)
but nothing happned.. not work,,
it make me sense,,,
because,, you can not choose high Resolution Level.
untill you willset sub-D about mesh (eg create sphere), nothing happen.
then,, you can set sub-D,,(if it had not been setted sub-D) from scene tab menu,,I do not remember,, it was same as ds 4.0.3,, ^^;
I believe I am right ^^; if I am wrong,, maybe Szark or another member help me,,^^
if you had known already,, such basic things,, not angry me ><; I am afraid it,,,
I am only 7 yeas old boy,,
(about,,3d and ds,,not year,,month,,)
