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!
