Polysuperficie different V5 on Windows 10 and Windows 7

Hi Rhino team
The two pictures attached show how these two polysuperfici shaped diamond are completely different if you draw in windows 7 and windows 10 using the same version of Rhino 5 SR13.
As seen in the Windows 7 version consists of 25 flat surfaces while the one in the Windows 10 version is made up of just 2 surfaces one flat and one not.
The problem is that in W7 version i can change the shape by moving the control points (solidPtOn) while in the W10 version I can do it only for the top surface.
The diamond is obtained starting from a sphere and by making the Rebuild with 8 points in U and 6 in V with degree 1 in U and V.

Hey Vittorio,

Check and see if you have _CreaseSplitting set to No on your Win 10 install…

You can fix the un-split one using _DivideAlongCreases _SplitAtKinks=_Yes.
