When you use the brush (not the pencil) every line is actually anti-aliased. How you describe it, I think it has more to do with the resolution of your image to start with. The thing about larger images (more pixels to start with) starts within Poser. You have to render in a new window with twice the size you want to end with (or maybe triple). Enlarging a 72 dpi render in Photoshop, working on it and then make its original size again has a blurring effect, and degenerates the original pixel information that Poser put in it. A bit of a trick is to do the unsharpen mask thing before scaling down, because it has a bit of an anti-antialising effect. It brightens pixels next to contrasting areas. Doing this on images with not a lot of pixels make the blocky appearance worse. Oh, I just thought of one thing. When scaling in Photoshop, use the bicubic option, otherwise you are enlarging or scaling down the pixels instead of the image. I mainly use Photoshop for print, so I work in 300 dpi all the time. Even then I do my retouche on larger versions to start with, and scale them down when I am done. In that situation I never have problems with the hairs I draw on Poser renders. When I scale the stuff down for Web use, it looks rather natural. The only thing you need is a bit of processor and plenty of RAM. Good luck experimenting, and when you have any questions or example files I would be glad to help out. Ruud
