Quote - Rendering at higher resolution without AA, and caling the image down in Photoshop using "bilear" sampling does indeed the antialiasing for you. This trick is used by major studios to cut down their rendr times. Takes less time to render bigger without AA, but somtimes it is not satisfying. But works most of the time.

Bruno could you please explain how to do this for me. I have used PS for 12 years but I don't know this trick. What settings do I need and in Photoshop what do I use "bilinear" or something? Thanks
