What exactly does that mean? The only things I'm seeing online pertaining to those keywords involve the new Arnold renderer for Max 17...But it didn't exist in 2013 when these images were created.
:) Question? Why not Arnold? Brute force Pathtracing is a lot more accurate than a 'hack' like FG. Thankfully the days of endlessly tweaking settings in renderers are over. I spent years learning first MR, and then Vray. To think of all those hours spent on an old, shit PC tweaking long into the night...... :)
