Strange creased vertices

Postby optimaforever » Fri Nov 23, 2018 11:08 am

Hi Thom,
I have some strange bugs happening these days with creased vertices.
It seems the creased vertice won't respond to the crease command.
SubD tries to crease some vertices but when I check the mesh, there aren't any crease on these vertices nor edges.
Very weird. It happened several times on different models.

It would help to see the model, but it looks like you have too many vertices on those edges.

Actually, if I delete and redraw these edges, the subdivision looks correct.
And the solid inspector doesn't show any error.

Unfortunately I haven't saved the mesh.

If you can save the model next time you observe this I can have a look.

It might be that you had a non-planar quad where the diagonal wasn't properly tagged to be compatible with QFT quads. Then the subdivision would subdivide each triangle and you will see that your loops becomes irregular after subdividing.
