With the release of 12.5 a few new Surface Operators have been introduced specifically the Wrangle nodes.To paraphrase the documentation “This is a very powerful, low-level node that lets experts who are familiar with VEX tweak point attributes and voxels using code.”

This workshop introduces the Houdini Artist to the VEX language for use in the Point, Attribute, and Volume Wrangle nodes. We will focus on the Point Wrangle. Once the basics of this “C”like language are explained, we will cover when you would want to use these nodes by going through several examples.
