Introduction to Houdini VEX and Python

This course covers the basics of VEX, Houdini’s expression language, as well as how to use Houdini’s Python API. We will look at the strengths and weaknesses and when you should favour one or the other. VEX is an essential tool for any technical director, so we will cover all the basics starting from its syntax, the difference between VEX and VEXpressions and how it can be used in SOPs and DOPs to optimize your systems. Later on, we will take a look at some more advanced examples like point cloud lookups and matrix transformations for dealing with deforming characters and finally creating a dissolve effect purely using VEX.
