thanks!

Hi!

What passes?

For some passes anti aliasing makes no sense, like for an ID pass where every object belongs to one specific color value.

[reniferziolo]

to be honest i used the id pass as an alpha mask and hoped there would be a way to alias it's edges without increasing the aa camera samples . You might ask why, i have some issues with the volumetric that dont render if i save the frame. (It used to save itself as the semi transparent ,why are the volumetric omitted if i save it as the image file that supports alpha?)

Change the filter to closest

Hi!

Without an example scene it's hard to say what's the problem with your volumetric object.

You can't anti-alias the ID pass, this would destroy the masks, as you don't know to what object any in-between color values belong. The only way is to render a higher resolution and scale down later in post.
