Students should leave this class with a new perspective on how to approach building liquid FX in more art directable ways, and discover new approaches in breaking down FX tasks into smaller manageable chunks.Learn procedural ways to mimic liquids without diving into DOP simulations. This class will show slimy drool, bloody trails, surface water droplets, and a flowing river.  All of the builds in this class will be made entirely with SOP nodes, and will showcase various techniques using common SOP nodes, primitives, curves, VOPs, and VEX to allow you to art direct your creation.
