Stundmann, bad AA is artifact!

Any graphical faulty in rendering is artifact!

cheers

Id like to know how to avoid this too in maya.

The only way ive figured out how to get around it is dong DOF in post..

its quiet easy, donīt use the cameras BG color -> color it in the post, so you will not get any troubble

try setting the depth type to closest visible depth and adjust range and clipping planes and maybe global AA settings

Rudity, uschi and miabe.

Thanks for the inputs. I think doing it in the post is best method for me.

This is a really common problem -- here is the solution.

turn on 2d (or 3D, but that is expensive) motion blur.

for some reason this trips an internal setting which causes the AA to be calculated with the post effects takan into account.
Silly really, but this has been the issue since about 2.5.

This also works to get rid of the bad AA when using Paint Effects too.

To be frank about it, Maya's DOF is not ver good anyway, so if you have a nice comping package like Shake or something you might do better to use that in conjunction with a z-depth map.

z-depth/paint effect and fur do not render with any AA....one of mayas more major f*$k ups..
