Hi Rich,

I just tried this in V2 and get the same result, it's just a graphical thing the surface is there when you export it and open it up in a poly or rendering program.

If you want to see the face put a value of 8 in 'Divide larger than' in the mesh settings also I noticed you've got such a low 'Angle' input at 4.61 where visual I get the same mesh with a value of 8 just curious why 4.61?

Cheers
