    Default White dots, MILA glossy reflections

    Hello everyone. I was experimenting with MILA shaders and got a problem. When I use glossy reflection layer white dots appear. I tried to enable filtering = 1 and some dots disappeared, but not all of them. Also I get much more of those dots when I crank bump values near to 1 in bump2D node.
    For current project I am using mrSun and Sky for lighting, but got the same issue with other types of lights.
    Any help would be appreciated.

    sun and sky could have very high light values, the primary cause of the dots when interacting with glossy reflection. Do you absolutely need them?

    Extreme bump also does not help. It can cause extreme conditions to create higher values. What was the roughness on the glossy?

    I hope you are using a gauss filter, and not mitchell or lanczos.

    Are you using exposure control in a lens shader? Or color management using Maya?
