In this Houdini tutorial, we'll learn how to create in-depth procedural FX tools. Throughout the lessons, we'll look at the steps required to build these tools from scratch. In the course we'll cover highly procedural approaches to creating a curve tangle generation tool and a particle flow simulation tool, while implementing our own particle system and particle forces from scratch, all without the use of a Houdini FX license. To achieve these tools, we'll extensively implement various VOP networks inside Houdini, which will allow us complete control over our setups. As we utilize numerous vector, trigonometry, and attribute manipulation techniques, you'll have gained invaluable knowledge on fundamental workflows and techniques that can be used to tackle problems faced as an Houdini FX Technical Director. By the end of the Houdini training, you'll have a solid understanding of how to approach procedural tool development, how to implement your own particle solver from scratch, and how to package it all up into easily accessible and artist-friendly Houdini Digital Assets. Software required: Houdini 14, Windows.
