Denoising and specular reflections Tweet

[HHbomb]

Hi,
I am very pleased to see how denoising works fine.
But I always have problem when having specular materials. With water, and glass.
See picture : a zoom in a render, all is fine except reflection in specular material.

I don't know if I could call this a problem, but if you're using only 500 samples and proportionally specular/reflection areas need much more Samples than simpler areas to calculate, like walls, it may be that in these areas there are so many samples missing that Denoise needs to smooth out the reflection.
