Hey guys,

I´ve simulated some splines with vellumhair and made some interesting knotes, while slowly pulling them.
The problem is, when I polywire them, I get these weird orientation/rotation flickerings you can see them in the gif.

Is there a way to fix this?

you can use Sweep SOP instead of Polywire
that can use p@orient attribute directly (as long as you used vellum hair and not string constraint)

if you need to use PolyWire for any reason
you can extract one of non-tangent axes as a vector attribute and enter that as Up Vector Attribue in Poly Wire
