Jagged edges... only in renders?
 

I can't for the life of me figure this out... I'm trying to render a treadmill model that a classmate modeled, and it renders with these really nasty jagged edges and thus shadows, despite looking fine in the viewports. It's not the lights, I don't think... I've tried all sorts of different light combinations and the problem persists. I feel like the problem is with the mesh, but how?

I think he made it using polys. He said something about this being a smooth proxy rather than a smoothed mesh, but I'm not quite sure what that means. Any ideas?

and the viewport:

Try setting your anti-aliasing settings to production....that should fix it.:ninja:

Hmm.... I'm using mental ray... where are the anti-aliasing settings?

Thanks!

Set it under Quality....and then play around with MotionBlur...and Sampling quality...dunno place a filter.....also check here for an example

If you are using Final Gather, bump up the number of rays. Also you should try experimenting with your min/max radius values. The min should be about 10% of the Max... a good start would be 1 and 10 respectively.
