This nearly killed my design workflow. Luckily, all of the MEL commands for subdivs still work. If you have a previous version, you can figure this out via the script editor.
And no, smooth mesh is not comparable in any way to the power i get from using subdiv surfaces. They allow more resolution with better control (i.e. moving a smooth 5-6 sided suddiv with 5-6 vertices at full crease to simulate a saddle surface). Full, partial crease and refine selected were great tools. The second that tools like this stop working completely will be the moment that I switch to C4D.
Just like that ? Can they at least explain why and how to get the same result. At least it could have been left as an option.
Moreover no mention in the What's new document. This What's new document, by the way, is not available in pdf for printing.
Not much concern about customers wishes.
