I know that the AA is much better now, but here I think a big difference really comes from the lighting. I am rendering a scene using these Sugar Maples Marc made. They look fantastic. I was getting render errors with the translucency setting Marc had. I deleted the translucent node, and they are rendering correctly.
I set the AA to 10, and the edges are sharper than Ryan's, but the 'whole' image Ryan did looks better than my render. Anyway, it should be done Wednesday. It might be good to compare the two images. Maybe both of us can write up a quick tutorial about our methods. I know Ryan could teach me quite a few things. Maybe someone could learn from me also.
