Vellum 101 - Manually Creating Vellum Constraints
Added 2019-01-10 09:00:59 +0000 UTCEDIT: As Morgan pointed out in the comments, I made a huge mistake by setting my geowrangles to run over points. I've attached a second scene file with correct geo wrangle settings. Thx, Morgan.
When you're trying to create silly string in Vellum it suddenly hits you - you have to wrangle your own constraints in DOPs.
In this tutorial we'll tackle creating a silly string setup including manual constraint creation and a neat little hack to our Vellum Source DOP.
Here's the link to cgwiki I mention in the video:

Great Tutorial! Is it possible to have more than one point generating the polyline? I am a newbie in Houdini, and I tryed to add two points in the add points nodes, and everything messes up.
