Ziva VFX 1.4 adds real-world physics to character creation

Ziva Dynamics has launched Ziva VFX 1.4, a major update that gives the company’s character-creation technology five new tools for production artists. With this update, creators can apply real-world physics to even more of the character creation process — muscle growth, tissue tension and the effects of natural elements, such as heavy winds and water pressure — while removing difficult steps from the rigging process.

Ziva VFX 1.4 combines the effects of real-world physics with the rapid creation of soft-tissue materials like muscles, fat and skin. By mirroring the fundamental properties of nature, users can produce CG characters that move, flex and jiggle just as they would in real life.

With External Forces, users are able to accurately simulate how natural elements like wind and water interact with their characters. Making a character’s tissue flap or wrinkle in the wind, ripple and wave underwater, or even stretch toward or repel away from a magnetic field can all be done quickly, in a physically accurate way.

New Pressure and Surface Tension properties can be used to “fit” fat tissues around muscles, augmenting the standard Ziva VFX anatomy tools. These settings allow users to remove fascia from a Ziva simulation while still achieving the detailed wrinkling and sliding effects that make humans and creatures look real.

Muscle growth can rapidly increase the overall muscle definition of a character or body part without requiring the user to remodel the geometry. A new Rest Scale for Tissue feature lets users grow or shrink a tissue object equally in all directions. Together, these tools improve collaboration between modelers and riggers while increasing creative control for independent artists.

Ziva VFX 1.4 also now features Ziva Scene Panel, which allows artists working on complex builds to visualize their work more simply. Ziva Scene Panel’s tree-like structure shows all connections and relationships between an asset’s objects, functions and layers, making it easier to find specific items and nodes within an Autodesk Maya scene file.

Ziva VFX 1.4 is available now as a Maya plug-in for Windows and Linux users.
