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.

Maya 2018 Speed bug Notice:

Maya 2018 has a bug that causes really slow mesh performances if you use more than 1 simulation substep per frame (zSolver.substeps > 1). This error is independent of the Ziva VFX plugin. Please update your Maya version to fix this problem.
If you're stuck with Maya 2018, don't worry. We found a 2018 workaround: 

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.

Marvel's Hulk & Spiderman

Bringing all your fan favourites to life, Goldtooth used Ziva VFX to simulate the incredible Hulk and Spiderman for Marvel's highly anticipated Marvel: Realm of Champions mobile RPG game trailer. Find out how they used 2 different Ziva techniques to make it happen.

Bringing the top characters to life

"Ziva software was instrumental in helping Sony create the most realistic muscle and skin simulations for our CG characters to date. Pipeline integration was effortless and ZIVA's outstanding results speak for themselves."
Chris Waegner
CG Supervisor, Suicide Squad Sony Pictures Imageworks
"Creating realism in creatures and humans has always been challenging, Ziva makes that journey much easier with impressive lifelike results."
Devan Mussato
Rigging Supervisor, ScanLine
“We've integrated Ziva VFX into our CFX pipeline recently. Ziva’s support is very responsive and of high quality, with years of experience in how to best setup your FEM muscle sims.”
Pascal Chappuis
Head of Technical Productions, Image Engine
“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.”
Theo Facey and Stephen Tong
Creature Development Team, Double Negative
"Ziva is dramatically advancing the fidelity of real-time virtual characters. Pushing their technology forward aligns with the creative and technical vision at Epic."
Kim Libreri
Chief Technical Officer, Epic Games
"We've been using Ziva for a while now and on several shows we have going here. It's brilliant and fast and useful for so many things that are not just muscular related. It’s the new ‘need-to-have’ software here."
Tim Mackintosh
Head of Animation and Creatures, Rising Sun Pictures
