Houdini Practice Hour: Modeling fully procedural

Ok, Friday is release day and the next “Houdini FX Practice Hour” project has started. We will start this week building a Coffee Cup Scene with some beans flying around. Also, we will dive into “procedural” Polygon Modeling in Houdini FX and, later for the beans, into Retopo and Rigid Bodies.

So, for people coming from other 3D applications, you will find a whole bunch of important Houdini FX concepts like selection, groups, automatically generated groups and channel expressions with HScript. Everything step-by-step, so that you can build your own scene.

Let’s start this week with fundamentals and build these paper cups – procedurally.

Thanks and have a nice weekend,
