Shimmering or buzzing effect removal?

[Kinetic99]

Hello and thanks for your time,

I rendered a very reflective object with many fine lines running along it that are close to each other. In a high res image, they look good and distinct but when you make the image smaller or print it as a small frame, the lines get compressed and there is a buzzing or even a "morré" pattern.

What are good rendering parameters to remove this effect completely?


My rendering was: 3000 x 3000,
adaptive DMC (apaptive noise at 0.005 and noise threshold at 0.01),
Antialiasing on with Mitchell-Net (Blur 0.4 and Ringing 0.3),
Sampling at 1/6


Please help, thanks. K

you might want to avoid sharpening filter, use area or quadratic to remove moire. For fine lines you need higher min sampling in dmc sampler. Something like 3/16 should do the trick.

thank you sir, I'll try that out again!
