Peter Quint gives us a great, concise look at compositing a rendered model over a live action plate using Houdini in this tutorial spanning four parts.

This series looks at a more advanced compositing workflow – compositing a rendered model over a live background plate. In this first part we create the scene, apply textures to the model, add the background plate and position the model. We then add and adjust a shadow casting light. The project file is available from here.
