I have noticed certain objects still seem "jaggedy", even after a render is complete and the other items are convincingly smooth. Does anybody know why this happens? (The offending items have tended to be square, and placed at an angle that makes them look skewed in the camera perspective.)

Antialiasing isn't a selective process. It either affects the entire scene or it isn't enabled. Can you post an example image?

If it matter, I had that same issue for a long time. I altered the settings in my geforce 4 video card, for the first time (cranked up the antialias setting w/in it) and WHAMO! thar graphics (that I thought were stunning quality anyways) came ALIVE. I wasnt using the vid card at its potential....dont know if this'l help you, but it also "woke up" my poser renders

It may be a result of the mesh... Poser tends to "round off" corners etc.. and sometimes it causes scallops along edges....things to try: check it with a texture applied, ensure the reflect and highlight are set to "Black" (colourwise within the material editor) I'll try to think up other things as the day progresses... good luck!

Hmm...interesting that you suggest setting reflect and highlight to "black." That white box is actually intended to be, in the final image, a mirror. It seems from other postings in the forum that my best best in getting a reflection is to do it through postwork, so maybe, for the sake of the anti-aliasing, I simply should follow your advice. I suppose I can always take care of the jaggys in postwork as well, but it's annoying that they exist. raz, I'm on a Mac, with Poser 4. Is your suggestion still applicable?

I think it is antialiased, but as a result of high-contrast, it still looks jagged. I've felt for some time now that P4's antialiasing and bump-mapping were particularly weak (although it's still better than none at all). I usually render at a much higher resolution and then sample down to the final size in order to get rid of some of the remaining jaggies.

Ahhhhhh.. a mirror 8 ) unfortunately Poser gets really confused with reflective surfaces... and you'd have to "fake it" 8 ) then again the proggies that can handle "true reflections" usually run in the $1000-5000 range 8 hrmmm... try setting transparancy to about 50% then posting the mirror's image? that way you have the outline, a little "fuzzing" for placement 8 )
