This is my first tutorial dedicated to Shade, but which also use Amapi Pro: it will show you how to export a NURBS object, export it as an OBJ file, and then, taking care of the tesselation, and in Shade, how to do a simple rendering with a Skylight and a HDRI map.
It works with Shade 8, 8.5 Std and Pro.
Please, be kind, it's my first tutorial related to Shade
I hope it will help you! I'll post the final render later!
