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

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.

PHYSICS

Add a physical-correction on top of any existing character rig with our goaling attachment. This lightweight approach corrects unwanted stretch, and adds contacts and secondary motion.

ANATOMY 

Design remarkable characters powered by science. Ziva VFX lets you create interdependent muscle, skeletal, and tissue networks that mimic anatomy and maintain biophysical accuracy.

VOLUME

Build characters easily as a single volume on top of a skeleton. This approach is ideal for feature animation - capturing the bulk, volume, contacts, and secondary dynamics of a character.
"It is the best muscle plugin we've found. It brings extra realism to our creatures via physically plausible muscle FX. It is a great improvement to have Ziva integrated into our workflow."
"Ziva was instrumental in helping Sony create the most realistic muscle and skin simulations for our CG characters to date. Ziva's outstanding results speak for themselves."
“Ziva’s FEM muscle and skin simulation was the last piece of the puzzle we'd been longing for to achieve realistic looking, physically plausible Creature FX.”
