millsy Posted August 18, 2020 Share Posted August 18, 2020 (edited) Hey everyone, I'm trying to create a sim with a circle that's emitting particles from which I create curve trails that are then given string vellum constraints. Up until I add the vellum solver node everything works fine but once the display is set to the solver my geo is no longer visible. I'm not really sure why this is - I'm wondering if it could be to do with the constant stream of particles and there being no real ‘start’ and ‘end’ to the wires? I'm still pretty new to Houdini so there's probably a smarter way of building this, I've attached my file if you've got the time to have a look. Any help would be appreciated.

jamesearnest244 Posted September 26, 2021 Share Posted September 26, 2021 (edited) This is ancient, but I'm having just the same problem. The Vellum Solver can't seem to accept a growing trail as input geometry. Does anyone have an idea how to crack this? I thought about using a Carve node after the sim, but unfortunately that's not gonna work in my case.
