Vellum is a unified solver that offers fast production workflows for cloth, wires, soft bodies, balloons and grains. It works a little different than other Houdini tools you may be used to, so this course is intended to help you understand the fundamental design intentions and usage techniques for this unique solver.

The Vellum workflow offers easy setup and control, is OpenCL / GPU accelerated, and has some powerful visualization options as well. In this course we will explore some of the key nodes and concepts for working with Vellum including Configuring Vellum objects, creating collisions, understanding constraints, and the "Post Solve" workflow.

    Great examples, pacing, and explanations. Glad this was the first one on the new Cloth page. I had stumbled around for a good intro, but this felt like a proper introduction for what I needed to understand.
