Weird Raytrace Result

This ring seems fine in all aspects until I try raytracing.

And here’s the file itself
Callaway Jim Kitty SubD 2.3dm (9.7 MB)

Any clue? Last thing I did was move some edge curves on one of the leaves using soft transform.
And the update is that when I closed the file and reopened it worked fine. Temporary glitch! :slight_smile:

That looks weird indeed. As if more geometry got transform than just edges.

Let me know exact steps if it happens again.
