Antialiasing question

[Strob]

Hi!

I thought I would post my question here since it's a bit hard on Facebook to follow up:

So Andrey, you told me on Facebook that antialising is controled automatically. but I have pretty high settings with everything fine except some antialising problems in some areas. Do you have any idea how I could get rid of it? Increase samples or lower threshold even more until there no antialising problems or else?

Here you can see on this video I have some antialiasing problem on the silhouette, on the cheek, chin, neck and eyes. I circled the problematic areas in red. i have a small bump all over but the problem was there even without bump.https://www.youtube.com/watch?v=zUEkkemNkYM&feature=youtu.be

you can compare with the V-ray version: same setup with little bump too but no antialiasing problem. https://www.youtube.com/watch?v=3AzgGqQ96uo

you can see my setting on those grabs:

Talking about antialiasing I also noticed that even in your benchmark scene, if you look at the door window there is a very noticable bad antialiasing staircase. Could be a good starting point to try to improve antialiasing. On a still it's not so bad but in animation it's even more annoying. I know it's probably why you set image blur and sharp at 0,1 by default in the tonemapping but I think it's not enough. There should be some way to improve antialiasing without blurring the image.

AA on bright edges is always a paint. The only way is to use higher image blur value.
