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. Cheers
