Moov Physics Operator
Moov Physics is Ornatrix's in-house physics engine for simulating hair motion. The Moov Physics operator gives you a real-time interface to that engine, so you can simulate hair swaying, settling, and reacting to movement directly in the App. It is the operator to reach for when you need true dynamics rather than the faked motion of the Oscillator Operator or Gravity Operator.
Simulating hair
Add the Moov Physics operator to a groom and play the timeline to run the simulation: the hair responds to motion of the underlying object and to forces such as gravity, building up believable follow-through and settling. Because it runs in real time, you can adjust the simulation and immediately see the effect.
Scriptability
Moov is extensible through Python. It ships with scripts that provide different simulation behaviors, and technical artists can write their own to achieve more complex or specialized results. See Scripting with the Python Console.
Working with simulations
- Set the frame range to cover the motion you want to simulate.
- Simulate a sparse set of guides and let the dense hair follow them, which is far faster than simulating every hair. See Adopt External Guides.
- Once you are happy with a simulation, bake it so it plays back without recomputing. See Baking Hair and Guides and Animation Cache Operator.
