Stiffness parameter controlling longitudinal strand stretching. Stiffness parameter of lattice nodes (used for constraints within a single lattice node).

To have meaningful lattice twist, the LatticeSize value has to be comparable to the distance between neighbour strand vertices. Lattice Sizeĭistances between the particles of a lattice node (corresponding to a single hair vertex). Cosserat models are preferred for applications where twist is important (e.g. A lattice can be used to simulate some twist response in models with only distance and bending constraints (i.e., non-Cosserat and non-elaston models). LatticeCount = 1 corresponds to simple longitudinal particle chains. Number of simulation particles corresponding to each hair vertex. if the scene units are centimeters, set this parameter to -981 (cm/s^2) if the scene units are meters, set it to -9.81 (m/s^2). Use to impose appropriate length units in the scene: e.g. Use to impose a speed limit on fast-moving hair simulations.

Maximum speed of particles in the solver. More iterations means slower simulation (although the effect is smaller than the previous parameter) and stiffer constraints (up to a certain number of iterations after that the constraint response is saturated). The difference with the previous parameter is that this one only affects the constraint response (not collision detection). Number of iterations in constraint projections. Larger values lead to slower simulation, more accurate collisions, and stiffer constraints (except in compliant models, which are less affected by this parameter).

Number of simulator steps within a single animation frame. Moov Simulation Parameters Solver Parameters Substep Count To enable collisions with the base mesh, set "Collide With Base Mesh".

The base mesh of the hair system cannot be added in this conrol.

Meshes added here will participate in collisions only if "Collide With Meshes" is set in Moov Simulation Parameters.

First add the mesh to the scene, then add it to the simulation using the Add Collision Mesh button. Used to add/remove Maya meshes to the simulation. To do that, first add the force field object to the scene, then add it to the simulation using the Add Force Field button Collision Meshes Used to add/remove Maya force field objects to the simulation. The resulting state is set as the initial state of the simulation. Starts an internal simulation, detached from the Maya GUI, and runs it until the particle position changes fall below the threshold (currently 0.1). At the first animation frame, the simulation is initialized from the previous node in the stack. At first animation frame, the simulation state is reset to the initial state. If an initial state already exists, it is replaced. Initial state buttons Capture Initial State buttonĬaptures the current state of the solver and makes it the initial state of the simulation.

The script is stored and saved with the Maya scene if the script on disk is changed (by an Ornatrix update or otherwise), Reload has to be pressed to update the script in the scene. This document refers to the parameters of the default Moov script that is loaded when a new node is created different scripts may create a different set of simulation parameters. Moov Simulation Controls Python File Name and Reload buttonįile name of the Python script for the simulation. Contrary to our Dynamics Operator, Moov does not depend on nVidia Flex and can be used in any OS or graphic card. TDs have the possibilities to expand MoovPhysics developing their own Python scripts to achieve even more complex and accurate simulation. This node provides a simple interface to work with hair simulation in real-time and a set of Python scripts to add new controls and expand its functionality. Moov Physics is designed to provide the artist and TDs with different algorithms to simulate hair movement.
