Saw profile in vray blender

Can some one tell me why occour this problem?

Antialiasing and high contrast area…Or texture has too narrow bleed margin.

this image was rendered with BF+LC with 1-100 subd(universal settings) but the problem it’s evident,and don’t occur in the same scene in 3dsmax

Put white backround to that also and try again. Like eppo said its high contrast area, dark and light crossing. If you set background to grey then there is less contrast and you will not see jagged edges.

I have done some experiment with dome light invisible and it happen that subdivision don t’ affect AA if ther is a texture in the

this shot was done with AA =0
this with subd min to 1 and max to 4, if i put a texture in dome light changin subd have not effect.
