I have got a strange behavior of the simple Frosted Glass Material in Rhino. There are three identical simple geometries (i created one and then copied it), to which I gave the same Frosted Glass Material. When these geometries are under direct sunlight, they look almost the same (which is also strange), but when I have a ceiling, thay start to look very differently. See the attached images.
I am using:
Rhino Version 6 SR11 (6.11.18344.20091, 10.12.2018)
Enscape Version: 2.4.1
