Since last year, I have wanted to learn how to use Houdini, and this is the result of half a month of studying and working in Houdini Apprentice. I started by watching videos on the Houdini learning platform to understand the software's basic functionality and YouTube videos to learn how other tools and nodes work. In this series of three crystals, I only used Houdini to create the geometries. I exported the .obj files to finish the 3D and render them in Blender. The compositions were made in After Effects.
