to the devs:
Finding - using the latest daily - i noticed one of my current scenes (a simple bathroom scene) took 18 hours to complete (5K render on a Ryzen 3970).... baffled me why it took so long when other renders take between 2-4 hours for this size. I then started to diagnose the issue and narrowed it down to the UVWrandomizer. The high quality blending takes the longest while without this checked, its a little better but still longer than without using the UVWrandomizer altogether.
When i removed this UVWrandomizer, the scene rendered in just under 4 hours. I realise you tooltip says it takes longer to computer (double in the worst case scenario), however in my case it was 4x longer.
Just a heads up.
