I have an issue with frosted glass in animation. There is a lot of noise(splotches) on objects with these materials. I’ve noticed that by eliminating the refraction glossiness, the noise disappears. Is there a way to fix it? If you need, I can share some examples. Thank you
I think the only solution right now is to reduce the value of “clamp secondary rays”.
How are you lighting the scene besides an HDRI ? It it self-illuminated materials ?
Have you tested V-Ray ? Does it have the same problem ?

Good morning, thank you for the quick response.
I will try to perform a test by lowering that value.
In the scene, in addition to the HDRI, there are some area lights and various emissive materials. Unfortunately, I have not tested Vray yet.
I thank you once again.
Hello, quick update…I fix it lowering the opacity of the glass materials!
