Extra vertex in geometry crash the mesh with subsurf modifier in V-ray

[kontrolermpl]

Hi,

I've a problem with meshes with some extra vertex (I use it to define centre cursor and after that I don't remove it) and subsurf modifier added.

In Blender view port all is fine (geometry on the left side has extra vertex).



But after render with V-ray I get something like that:



I attached also blend file:

Subsurf_damage_test_v02.zip

Well, I could try detecting isolated vertices...

bdancer, something new to this issue?

Since you could just remove such vertices, this issue is at the bottom of my list sorry.

O.K. I'm patient, I know, that worth.
