You're right, I typed 1 instead of 2. I've fixed the forum announcement, but I have to talk to the web guys about fixing it on the early builds site.T0M0 wrote: (there is small typo 18.104.22.168)
I'll copy the note from the announcement here, to make sure everyone sees it:
The viewport render engine defaults to "OpenGL - Core Profile" in Maya 2016 Extension 2. Maxwell material previews and some custom draw objects (e.g. grass and sea) do not work with this render engine. To see Maxwell materials and custom objects in the viewport, you need to go to Windows -> Settings/Preferences -> Preferences -> Display and change the "Rendering engine" setting to "OpenGL - Legacy". This compatibility issue will be resolved in a future plug-in update.
