This masterclass will cover new Vellum constraint features in Houdini 18, some of which are workflow enhancements. This includes automatically computing mass and thickness based on density, making it easier to work with geometry of different resolutions. Normalizing stress computations over substeps, will save you the hassle of having to adjust threshold values when changing substeps. For the new constraint features, there are Stiffness Dropoff, Tangent Stiffness, Stitch to primitive location, Sliding for Stitch and Attach constraints, and ARAP constraints which are effective for simulating organic material/softbody and things that require good stretching and compression behaviour.
