Hey everyone. I’ve been digging a bit deeper into Vellum and I’ve kind of hit a wall, so I’m hoping someone here might know the answer.

What I’m trying to figure out is how to emit continuous Vellum geometry, like a spaghetti strand or a tube. Right now I’ve got a super basic setup where I emit a point every frame and, inside a SOP Solver in DOPs, I connect those points into a line using an Add SOP. That part works fine.

The problem is when I try to add Hair Constraints everything goes sideways. I have a feeling I need to filter which polygons get the constraints, but I’m not quite sure how to approach that and I’m getting stuck there.

Would appreciate if someone could give me a hand.

I’m attaching the setup as it is before adding the constraints, in case that helps.
