Specular Pass strange noise

[Alvaro Letelier]

Hi. I getting strange noise and butterflies on my spec channel pass only. Any recommendations to avoid this issue. All other channels, GI, Reflections looks cool. At the moment rendering using Image Sampler at Min Sub :1 Max Sub : 24 Threshold: 0.008. DMC Sampler at default. Animated noise pattern: ON.

Increasing the Min shading rate and decreasing the Noise threshold a bit should make things better. If that doesn't help you can try increasing Min Subdivs to 2.

Hi. Yes. Adjusting the Min Shading solved the problem. Thanks!
