If I make Cycles render at a low sample count, then there are not that many anti-aliasing samples.

If I make Cycles render at a higher sample count, then there are more anti-aliasing samples and generally less noise.

How you render with the path tracing noise of low sample count rendering, and with the anti-aliasing quality of high sample count rendering?

I thought about making all of the lighting in the scene be caustics, but it might not have enough noise at enough samples for high quality anti-aliasing.

Maybe doing something like this would work.

Is there a better way, like some way to arrange the samples, such that it makes lots of noise and high quality anti-aliasing?

If so, how?

There is an anti-aliasing node in compositing. Have you tried rendering with few samples and then post-processing the result with that node?


  • $\begingroup$ That node might not produce anti-aliasing that looks like anti-aliasing with the box pixel filter. $\endgroup$ Aug 3, 2022 at 3:56
  • $\begingroup$ Also, If I render something at more than one samples per pixel, such as 2 samples per pixel, then there would be 2 anti-aliasing applied to the render. Also, using the node to do it seems kind of hacky. $\endgroup$ Aug 5, 2022 at 3:11
