That sounds intriguing. Can you elaborate? I don't think there are AA controls within the compositing tag. Do you just mean to run off some object buffer passes?

OK, I've never used this myself so I'm no expert but there are AA settings in the Compositing Tag under a check box called Force Antialiasing and then you have the same settings as in the AA tab proper. I assume that this Compositing AA setting allows you to set the AA however you want it for the individual object that the tag is attached to and independent of the main AA settings. This would mean that you could push the AA up just for the problem items and so keep your render hit to a minimum. Check the documentation, or maybe someone else can put me straight on this if I've got it wrong.

I've never even noticed that. I'll definitely check that out, thanks.

Phew, so I didn't just make a fool of myself! [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/laugh.gif[/img] This would mean, depending on how many problem areas you have, that you could absolutely max the AA on those and not take much of a render hit.

yep, try it on a big scene, you will notice the difference, composoting tags used wisely save you lots of time [img]http://www.c4dcafe.com/ipb/public/style_emoticons/default/thumb_yello.gif[/img]

That technique is really going to come in handy!
Thanks again, guys.
Thanks again, guys.

yep, force AA on the object and its fixed. another thing to remember is that any fine details/edges which are reflective or transparent will render differently every frame unless you force the AA up to at least 8x8 to smooth out the discrepencies when rendering an animation. its usually good practice to antialias with as low a threshold as you can too.
I love a good Epiphany. The more the merrier!
