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

The Toolset to replicate physics

Ziva VFX can be used on any soft-tissue asset including complex, lifelike characters/creatures, 3D feature animation, and inanimate soft objects. Ziva's advanced character tools let artists replicate the effects of physics and recreate any material, including muscles, fat, and skin.

Faster changes

Character alterations can be applied retroactively at nearly anytime. Simply adapting the underlying anatomy of your characters will allow you to react faster.

Greater Control

Muscles preserve volume under force and collision, and the tissue will bend, stretch, crease and jiggle with the realism audiences and experts expect. 


ZIVA VFX lets you improve fidelity, modify appearances, and shift art direction while still preserving the character essentials. Never start from scratch again.
Add Dynamics to Existing Rigs
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 plausible secondary motion.
make FEATURE ANIMATION with physics
Create rudimentary characters easily with a single volume on top of a skeleton. This approach is ideal for feature animation - capturing the bulk, volume, and secondary dynamics of a character.
Correct Trouble Areas
  1. – Correct hand pronation-supination
  2. – Correct neck shape with precise neck muscle movement
  3. – Correct upper-body rigidity under twisting
  4. – Correct thigh skin shape due to quadriceps muscle excitation
  5. – Add life-like belly fat secondary motion (inertia and gravity)
  6. – Correct elbow self-collisions
“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.”

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.
