Driving Fluid Simulations with Video

Here we learn how to drive Flip fluid simulations with video data in Houdini by utilizing motion vector passes (optical flow) generated from Nuke. This is more or less a description of the technique I explored here: vimeo.com/229933717

This tutorial assumes some working understanding of Houdini 16 and it's interface. Topics covered include a brief talk about attributes, some vex, and some FLIP simulations.
