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.

Director feedback at the 11th hour? Character alterations can be applied retroactively at nearly anytime. Adapting the underlying anatomy of your characters will let you react quickly to all feedback during any step of your creative process.
With soft tissue sitting on top of anatomical muscle groups, everything looks right. Muscles preserve volume under force and collision, and the tissue will bend, stretch, crease and jiggle with the realism audiences and experts expect.
When the inevitable prequel, sequel, and spinoff get the green light, ZIVA VFX lets you improve fidelity, modify appearances, and shift art direction while still preserving the character essentials. Never start from scratch again.
