Maya 2018 Speed Notice:

Maya 2018 has a performance bug causing meshes, that normally take a few milliseconds to process in Maya 2016, to take multiple seconds in Maya 2018. This is independent of Ziva's plugin and can easily be triggered entirely with built-in deformers.

If you're using more than 1 simulation substep per frame (zSolver.substeps > 1), then this Maya problem may be triggered and can significantly slow down everything.

The workaround is to set Maya to playback at the same rate as the solver substeps. For example, if zSolver.substeps = 4, then set "Playback by" in the Time Slider preferences to be 0.25 = 1/4 to match.

Damping update tip:

When zSolver.maxNewtonIterations is greater than 1, the dynamics were often under-damped. The dynamics are correctly damped now, which will result in some simulations appearing more damped than before. To recover similar results to previous versions, decrease zSolver.stiffnessDamping and zSolver.massDamping – possibly to the new default values: 0.001 and 0.0 respectively. This

Bodies in Motion

Ziva bodies represent the actual physical forces at play when humans move. Sports Science and Human Biomechanical Movement teams can use this software to generate visualization and training data from an infinite number of human motions and poses.

Coupled SImulations

Skin and fat affect how clothing fits. Clothing affects how are our bodies feel and move. Wind and water affect how our bodies move, jiggle, and “deform”. These types of coupled simulations - and more - are available for exploring further in Ziva technologies.

Physics-Embedded Faces

With so much available research and demonstration of AI/ML techniques for recreating virtual faces, Ziva’s technology effectively pairs AI with physics simulation for a better result.
