GREATER REALISM

With soft tissue sitting on top of anatomical muscle groups, everything looks right. Muscles preserve volume under force and collision, while tissue bends, stretches, creases and jiggles with physics-informed realism.

FASTER ALTERATIONS

Director feedback at the 11th hour? No problem.

With ZIVA VFX, 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.

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

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

Add life-like belly fat secondary motion (inertia and gravity)

Correct elbow self-collisions

Bug Fixes

Fixed a bug where Maya Fields did not evaluate correctly if the solver transform changed after the first frame.

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 was fixed in 1.4’s initial release, but missed in the release notes.

Fixed a bug where a “Solver has encountered instabilities” message persisted even after rewinding to the first frame.

Fixed a bug where adding a new body to the scene could affect the simulation results of existing, unconnected bodies.

Fixed a bug where zBuilder would sometimes not record the field and zFieldAdaptor nodes.

Fixed a bug where zBuilder would sometimes re-order zMaterial nodes.
