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.

the Same tools as the Top Studios

All Star Students


Students and recent graduates are creating high-quality characters, right out of the gate. With Ziva Academic Licenses, aspiring artists are gaining the competitive-edge needed to make it in the world's top studios.

Students like Seppe Vangrunderbeek, currently attending Howest Kortrijk in Belgium, have been making robust, physics-based creatures, right from the start. This anatomical bison was his first full creature simulation and took him a mere 2 and half weeks to build. According to Vangrunderbeek,
"Ziva is used in companies I want to end up in later, so this project was important to me. As a student, it I found Ziva very easy to learn. Whenever I ran into problems, I'd just used the Ziva forum and I was almost instantly helped by the Ziva Team. I enjoy it a lot!"

The Top Curricula

Visual effect schools around the world are adopting the industry's top tools to offer the most competitive programs to aspiring creators. In the August of 2018, TrueMax Academy, located in Copenhagen, Denmark, was the first certificate program in the country to offer a VFX program with a Ziva VFX simulation curriculum.

The intensive program taught students the fundamentals of a wide range of VFX disciplines, with the rigging and character creation division focused largely on simulating with Ziva VFX.

According to Lasse Rassmussen, the professional guest lecturer, currently working as a Creature TD at One of Us Studios in London,
"Displaying Ziva VFX knowledge in your reel and showing your ability to produce that kind of work is a ticket to working in the industry."

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.

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. 

RAPID CONTINUATION

ZIVA VFX lets you improve fidelity, modify appearances, and shift art direction while still preserving the character essentials. Never start from scratch again.

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.

"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.”
