... and a cycles for rhino 5?

Why do not think of a Cycles Renderer integration into Rhino 5?

The Cycles integration work as Raytraced mode is relying on enhancements in the v6 WIP as I understand it. I don’t believe it would be possible to make a version of this for v5.

A production render integration could be possible, but I personally don’t have time to work on that, as all my time goes into the v6 integration and RDK development.
