Flickering UVs on PolyWire

Hello everyone,

I have a wire sim. I am using PolyWire to mesh it and I procedurally UV unwrap it. The problem is that the UVs are jumping/glitching/flickering (please see the attached GIF).



It has to do with the Polywire rotating randomly along the spline at some frames.
Any idea how to stabilize it?

Hard to tell without an example hip file but i remember i had a similar problem and that i checked “Fix Boundary Seam” on the UV Texture node. Not entirely sure is that will fix your problem. It might also be related a changing number of points on the splines you are sweeping. But then again. Hard to tell just by looking at the images.

Thank you very much for a quick reply. I am pretty sure this is happening because of the geometry itself rotating randomly along the spline in some frames. The point count is not changing. I have no attributes to tell the PolyWire how to orient properly. I will try to fix it myself tomorrow. If it doesn't solve the issue, I will post a HIP file here. Once again thank you.
