I dont understand this. I'm using Maya 8.5 and just recently I purchased version 2008. It doesnt matter if I use a PC or a iMac... LCD or CRT screens... using a complex or simple scene. Using Mental ray, shadow maps or raytrace... HUGE anti-aliasing setting... or a small one.... tesselation is high or low... doesnt matter... When I render something and watch it in the render viewer, it seems the zoom is set to 1:1, but it actually shows 1:0.995 or so. I get jagged lines!!! When I save the same render out to a .psd file and watch it in photoshop... it looks as smooth as flowing milk. I simply dont understand this. Now I did make sure all settings are production level ... AA is set high etc etc... I tried clicking on 1:1 many times... zoom in or out then click again.. I tried it all. If I manage to see the .psd file all smooth and clean, there shouldnt be ANY reason for it to appear jagged and aliased in the render view. Here is an example: Render Viewer: .psd File: I added white background in photoshop to show how smooth and anti-aliased the pic is. so, if anyone knows what causes this and if there is a solution... I'm allll ears! : ) Thanks!
