ToonShader contour lines flicker

Hi,

Im using the aiToon shader in an environment with lots of detailed geometry and an animated camera. Toon seems to be giving me a lot of edge flickering artifacts which are very obvious with animated sequences. Even with 6 AA camera samples the issue persists around some corners.

I tried to decrease the edge detect angle threshold, which seems to work for some areas but not for others.

tldr: how do I remove those contour toon shader flickering artifacts ?

I would use adaptive sampling so that the problem areas get more camera samples while the pixels with simpler geometry can still get away with fewer samples.

Hello, we have a similar issue outlined here:
https://answers.arnoldrenderer.com/questions/36143/toon-shader-contour-lines-flicker-w-example-scene...

In many cases, enabling adaptive sampling makes the problem worse.

Still looking for a solution to this.

Thanks,
