ZIVA VFX – Visual FX Results

CREATE BETTER VIRTUAL HUMANS AND CREATURES BY MIRRORING NATURAL ANATOMY AND PHYSICS.

ZIVA VFX is a Maya plug-in with an offline Finite Element Method ‘anatomy aware’ simulator that lets you create life-like characters at scale.

Three Ways to Empower Your Characters

                        About

PHYSICS

Add a physical-correction on top of any existing character rig with ZIVA VFX's 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 true 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 your character.

Enchantress | Suicide Squad

With the help of ZIVA VFX, Cara Delevingne's character Enchantress in Suicide Squad achieved shockingly life-like detail, including:
  • Accurate skin bending at joints
  • Correct hand pronation-supination
  • Torso and neck rigidity under twisting
  • High-quality belly fat secondary motion
  • ...and more

Slimer | Ghostbusters

Ziva was used in the Ghostbusters (2016) movie to add plausible jiggle to the film's feature character Slimer.

From gooey, self-propelled monsters to stable, arbitrary elastic objects with collisions and self-collisions, everything comes to life with Ziva.

Graphorn | Fantastic Beasts

The hyper-detailed Graphorn from Fantastic Beasts & Where to Find Them came to life on screen and in VR with the help of ZIVA VFX.

Design characters and beasts with a range of material types for a variety of skins, scales, muscles, and textures.

FASTER RESPONSE TO FEEDBACK

Director feedback at the 11th hour? Character alterations can be applied retroactively at nearly anytime. Simply adapting the underlying anatomy of your characters will allow you to react quickly to feedback during any step of your creative process.

FUSION OF ARTIST CONTROL AND PHYSICAL REALISM

With soft tissue sitting on top of anatomically accurate 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. 

RAPID CHARACTER CONTINUATION

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.

“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.”
"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 VFX FEATURES

  • Take large timesteps with stable and invertible FEM
  • Use multiple material types, producing robust motion even under large deformations: StVK, NeoHookean, co-rotational, anisotropic
  • Collide objects using automatic collision detection and response
  • Add physical attachments between objects and paint where they are attached
  • Embed arbitrary triangle meshes into your simulated solids
  • Simulate thin shells (for skin)
  • Paint muscle fiber directions, then excite/contract a muscle using scripted muscle activation forces
  • Goal elastic solids to externally animated triangle meshes, for automatic addition of secondary motion
  • Paint nearly everything: attachment areas, muscle fibers, muscle strength, tet-mesh resolution, material properties
  • Use multiple types of physical damping
  • Cache simulations to RAM or disk for fast playback and/or restarting
  • Exactly preserve volume, even under large deformations
  • Script and pipeline your rig using Maya MEL, or using our open-source Python tools

+ Software requirements

  • Maya 2014, 2015, 2016, or 2017
  • Windows 7 (or higher), or Linux

+ Use Cases

  • Anatomically realistic character animation, including:
    – Anatomically accurate bending of the skin at the joints
    – Correct hand pronation-supination
    – Correct neck shape with precise neck muscle movement
    – Correct upper-body rigidity under twisting
    – Correct thigh skin shape due to quadriceps muscle excitation
    – High-quality belly fat secondary motion (inertia and gravity)
    – Correct elbow self-collisions
  • Cartoon/feature character animation with simple, single-simulation-mesh anatomy or complex, hyper-realistic anatomy.
  • Enrich existing baked animations with controllable and tuneable secondary physically based motion.
  • Modelling tool for reducing stretch and volume-change in sculpts.
  • Make and simulate arbitrary elastic objects undergoing collisions and self-collisions, from gel to plants to steel-beam bridges.
