Which begs the question as to why I was automatically directed to the version I downloaded which clearly forced me to install Rosetta before it would even open the installer. Interestingly, this link says that Alexander M from Chaos said that a non-Rosetta (native to M1) version of Vray was due in the first half of last year. I’m guessing you had to install Rosetta before you could get the VRay installer to run - probably you already had it installed? I wonder if it’s something to do with that. I wonder if somehow they have removed the latest Sketchup version from the Vray installer but that seems unlikely. Presumably you have the same issue as me: Sketchup 2022 just doesn’t appear in the list in the Vray installer dialogue boxes? Change the shutter speed in your Vray Asset Editor to make your space look. This just gets stranger and stranger! You have the same fundamental set up as me, but I have never been able to install VRay 5 in this combination and yet you, somehow, were. 0 for sketchup, a render, clear and clean as what we see in the picture below.
