Digital Tutors - Controlling Your Fractures in Houdini

In this Houdini tutorial we will learn the process to follow in order to pre-fracture an object beforehand to make it fall apart in a controlled manner.

To do so, we will use some Voronoi fracture in combination with a constraint network in the bullet solver of Houdini. We will break the network in a customized way in order to reach the wanted effect. We will then add some smoke and dust to complete the effect.
