Nice one, I set mine up to load arnold. I am going to test having it load an arnold material on the object and possible setup a quick light scheme. :D I just hacked the code of the GoZ Mel script and it worked. It just loads a blinn but will set Arnold to default. Instructions: Go to path…
They took Mental Ray out of Maya in newer versions of Maya 2016. In 2017 they replaced it with Arnold. If you search for it there is a separate installer for Mental Ray Maya 2016.
