Getting started

Install

  1. Put JV-FLIP_DOP_Controller-v1.0.hdalc in Documents/houdini22.0/otls/.
  2. Delete the previous version's file if you are updating — two files of the same type collide.
  3. Restart Houdini, or Assets ▸ Refresh Asset Libraries.
  4. It appears at Tab ▸ JV ▸ FLIP DOP Controller, at SOP level.

First setup

You need a DOP Network with a FLIP Object and a FLIP Solver already in it — this connects to a sim, it does not build one.

  1. Drop the node at SOP level, anywhere.
  2. Optionally wire in the geometry that defines your volume; that is what Match Input Size matches.
  3. Set DOP Network to your dopnet.
  4. Press Connect Parameters.

A report lists everything it wrote. From here the sliders on this node drive the sim.

Three things that look wrong and are not

  • The box vanishes when you select another node. It is guide geometry. That is how it stays out of your geometry stream.
  • The node has no output. Deliberate — it is a controller.
  • Voxel Size will not accept typing. It is derived. Set Drive By to Voxel Size to swap which of the pair you author.
