Ive spent the past couple days trying to figure this out. Now my time is running too low to be figuring it out without asking.
My final renders turn out with white spots. ive read soo many similar cases, but non seem to solve my issue.
I think I've narrowed it down to my VFB Reflections channel as the source (when i view it independently, its the one that doesnt look right).
I'm trying to create a polished concrete material, so it should reflect color and some very subtle geometry (chairs, walls, etc) similar to sidewalks when it rains, but with less ripple distortion.
I will attach images once the render is complete.. im only posting now in case someone knows off hand
*edit* Images
Order of appearance: Reflection, RGB, Raw_Light (i added this because there is some noise that im not sure if it contributes or not)
