Hi, my 3d objects have jagged pixels around the edge. This link mentions a fix, but I can't find it. 3d objects created from layers have jagged edges : Adobe Photoshop
How can I soften them so my output is realistic?
I do not have that issue on my machine (AMD 7970 3GB) - what graphics hardware do you have? My OpenGL settings are set to anti-aliased. Also, rendering the 3d object should render much nicer with smoothly anti-aliased edges (it does for me in CS6).
Did you render your 3d layer?
You have not provided exact system info or settings nor any other details, so nobody can even begin to guess.
