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.

Volume Preservation

Ziva’s advanced volume preservation capability is one of the key features that enables Ziva users to achieve more realistic deformation results than with any other character rigging software on the market.

Our plugin offers multiple ways to control, adjust, and perfect your tissue’s volume preservation levels using the built-in Material parameters.

Automated Muscle Firing

Ziva's Automatic Muscle Firing function was purpose-built to fill the needs of character creators

This capability allows creators to achieve natural muscle excitation results without any additional assistance from an animator or any inorganic shot sculpting. First, you must create a Muscle Fiber from a Maya object.
