 I considered the shock situation and the feeling of lost of the new artist when he open Houdini , So I Started simplify the different space of object like world space object space and how to use the Geometry spreadsheet !!!  we will do some modeling projects and I will show you how to create procedural modeling in Houdini with zero questions on how or why this is happened !!!  if you are new to Houdini or you come from other 3D software like Maya or Cinema 4D or 3DS MAX , you are at the right place, I designed this course to help new Artist get familiar with Houdini and give them wide idea about Node Based Workflow in Houdini FX, even if you are planning to learn creating VFX in Houdini, this course for you , because the procedural modeling is the backbone for all other stuff in Houdini !!!  controlling all the Houdini levels start from from SOP level or the geometry modeling level , so you need to improve your modeling skills in case you want to learn Houdini for creating VFX, Rigging, Animation or Motion Graphics !!!
