How do I get my renders to not antialias with the background? (Cycles) I'm currently working on a project that requires 2d-rendered sprites however I need for the sprites to have aliased borders/outlines with the background while the rest of the image is antialiased. I am using Cycles so I think the only way I can do this is through compositing.
How about this? See my attached screenshot. Rendered in cycles.
It is a very easy compositing node tree.

Is this what you expect? Antialiasing inside objects, but aliasing outside. Works with transparent background only.

Best wishes
