SubD objects do not display properly in Rendered, Raytraced, Artic and Atistic viewport display modes

I know SubD objects are not officially supported but this bug was not present in WIP/BETA builds.

Windows 10 (64-bit) 1709 (16299.192)
Rhino 6 SR1 (6.1.18037.13441)

Raytraced hasn’t ever supported SubD objects - support for it in the used ChangeQueue technology is not implemented yet.

Support for SubD objects will appear most likely in Rhino 7.

Once you have a subd object you are happy with you can _ExtractRenderMesh and use that for Raytraced

I used to convert it to NURBS but when more than two creases converge in one point it results in missing faces. Thanks anyway.
